edfe78aec9 Context operators for adjusting context values directly to avoid adding operators for adjusting single values which also need duplicate notifiers.
wm.context_set(path="scene.tool_settings.someattr", somevalue)
wm.context_toggle(path="scene.tool_settings.somebool")
wm.context_toggle_values(path="scene.tool_settings.some_enum", value_1="somevalue", value_2="othervalue") # switch between 2 values
wm.context_cycle_enum(path="scene.tool_settings.some_enum", reverse=False)

the path value is taken from the context so the full path is 
context.scene.tool_settings...

This means in keymaps you can cycle draw modes, change PET- anything with rna access.
If its not so nice to map keys to operators like wm.context_set we could use macro's to wrap it and have its own name

Use this for PET and setting pivot options

- Made userpref key shortcut Ctrl+Alt+U since its not used in 2.4x
- added pivot_point_align (Alt+Comma)
- added PET wasnt rna wrapped correctly.

3b8925c655 Particle Edit Mode:
* Fix crash trying to enter particle mode when the particle modifier
  is disabled in the stack.
* Fix redraw being very slow due to the draw function causing the
  object to be recalculated on each redraw (through PE_draw_object).

* Removed the system where PE_get_current would automatically create
  the particle edit, this would run from poll() functions, which gave
  all kinds of issues, now it only creates the data on enter/exit
  and switching active particle system.

3ebd58673f Key Configuration
Keymaps are now saveable and configurable from the user preferences, note
that editing one item in a keymap means the whole keymap is now defined by
the user and will not be updated by Blender, an option for syncing might be
added later. The outliner interface is still there, but I will probably
remove it.

There's actually 3 levels now:

* Default builtin key configuration.
* Key configuration loaded from .py file, for configs like Blender 2.4x
  or other 3D applications.
* Keymaps edited by the user and saved in .B.blend. These can be saved
  to .py files as well to make creating distributable configurations
  easier.

Also, user preferences sections were reorganized a bit, now there is:
Interface, Editing, Input, Files and System.


Implementation notes:
* wmKeyConfig was added which represents a key configuration containing
  keymaps.
* wmKeymapItem was renamed to wmKeyMapItem for consistency with wmKeyMap.
* Modal maps are not wrapped yet.
* User preferences DNA file reading did not support newdataadr() yet,
  added this now for reading keymaps.
* Key configuration related settings are now RNA wrapped.
* is_property_set and is_property_hidden python methods were added.

3816554cbc General particle bug fixes + few small goodies
The goodies:
* Curves can be used as normal dynamic effectors too with 
  the new "curve" field shape.
* Group visualization has optional duplication counts for
  each object in the specified group.
* Object & group visualizations, which are done without
  taking the dupliobject's global position into account
  (unless the whole group is used). This is much nicer than
  the previous behavior, but I added a "Use Global Location"
  option for those who want to use it the old way.
* The active particle system's particles are now drawn a 
  with theme coloured outline instead of pure white.
* Added object aligned velocity factors (buttons categorized
  and re-organized too).

Bug fixes:
* Absorption didn't work as the ui toggle button was forgotten.
* Some other force field ui tweaks.
* Crash after adding children and changing trails count.
* Display types "cross" and "axis" crashed.
* Particles weren't drawn with correct coloring.
* Billboards didn't update properly in viewport to camera
  location changes.
* Particle rotation wasn't recreated correctly from point cache.
* Changing particles amount crashed sometimes.
* Some files with child hair crashed on loading.
* Compiler warning fixes.
* Adding boids crashed on frame 1;

b26ef33b8e Fix #19311: adding/opening datablocks did not always make the right
one active. Now there's a function to get the pointer + property from
the UI, just like for the animation operators.

Also two fixes for fileselect events, regions are now preserved so that
context is restored to the old region, and the cancel callback is called
when the operator is cancelled.

15d81b21f6 Fixing scons compile on windows.
Since bli_threads.h now includes pthreads directly, we need to had instructions in SConscripts everywhere for proper include path.

Frankly, I feel like this should be done in a global manner and not in a per lib fashion, but that is for another day.

This commit also fixes more missing properties

bff893a420 Unified effector functionality for particles, cloth and softbody
* Unified scene wide gravity (currently in scene buttons) 
  instead of each simulation having it's own gravity.
* Weight parameters for all effectors and an effector group 
  setting.
* Every effector can use noise.
* Most effectors have "shapes" point, plane, surface, every point.
	- "Point" is most like the old effectors and uses the 
	  effector location as the effector point.
	- "Plane" uses the closest point on effectors local xy-plane 
	  as the effector point.
	- "Surface" uses the closest point on an effector object's 
	  surface as the effector point.
	- "Every Point" uses every point in a mesh effector object 
	  as an effector point.
	- The falloff is calculated from this point, so for example 
	  with "surface" shape and "use only negative z axis" it's 
	  possible to apply force only "inside" the effector object.
* Spherical effector is now renamed as "force" as it's no longer 
  just spherical.
* New effector parameter "flow", which makes the effector act as 
  surrounding air velocity, so the resulting force is 
  proportional to the velocity difference of the point and "air 
  velocity". For example a wind field with flow=1.0 results in 
  proper non-accelerating wind.
* New effector fields "turbulence", which creates nice random 
  flow paths, and "drag", which slows the points down.
* Much improved vortex field.
* Effectors can now effect particle rotation as well as location.
* Use full, or only positive/negative z-axis to apply force 
  (note. the z-axis is the surface normal in the case of 
  effector shape "surface")
* New "force field" submenu in add menu, which adds an empty 
  with the chosen effector (curve object for corve guides).
* Other dynamics should be quite easy to add to the effector 
  system too if wanted.
* "Unified" doesn't mean that force fields give the exact same results for 
  particles, softbody & cloth, since their final effect depends on many external 
  factors, like for example the surface area of the effected faces.

Code changes
* Subversion bump for correct handling of global gravity.
* Separate ui py file for common dynamics stuff.
* Particle settings updating is flushed with it's id through 
  DAG_id_flush_update(..).
  
Known issues
* Curve guides don't yet have all ui buttons in place, but they 
  should work none the less.
* Hair dynamics don't yet respect force fields.

Other changes
* Particle emission defaults now to frames 1-200 with life of 50 
  frames to fill the whole default timeline.
* Many particles drawing related crashes fixed.
* Sometimes particles didn't update on first frame properly.
* Hair with object/group visualization didn't work properly.
* Memory leaks with PointCacheID lists (Genscher, remember to 
  free pidlists after use :).

15d07720e5 Sorry, three commits in one, became difficult to untangle..
Editors Modules

* render/ module added in editors, moved the preview render code there and
  also shading related operators.
* physics/ module made more consistent with other modules. renaming files,
  making a single physics_ops.c for operators and keymaps. Also move all
  particle related operators here now.
* space_buttons/ now should have only operators relevant to the buttons
  specificially.

Updates & Notifiers

* Material/Texture/World/Lamp can now be passed to DAG_id_flush_update,
  which will go back to a callback in editors. Eventually these should
  be in the depsgraph itself, but for now this gives a unified call for
  doing updates.
* GLSL materials are now refreshed on changes. There's still various
  cases missing, 
* Preview icons now hook into this system, solving various update cases
  that were missed before.
* Also fixes issue in my last commit, where some preview would not render,
  problem is avoided in the new system.

Icon Rendering

* On systems with support for non-power of two textures, an OpenGL texture
  is now used instead of glDrawPixels. This avoids problems with icons get
  clipped on region borders. On my Linux desktop, this gives an 1.1x speedup,
  and on my Mac laptop a 2.3x speedup overall in redrawing the full window,
  with the default setup. The glDrawPixels implementation on Mac seems to
  have a lot of overhread.
* Preview icons are now drawn using proper premul alpha, and never faded so
  you can see them clearly.
* Also tried to fix issue with texture node preview rendering, globals can't
  be used with threads reliably.

854ea35a24 2.5: Handlers are now evaluated in a different order, fixing some
issues like Shift+R (repeat last) not giving capital R in the text
editor. There is also new modal handler list at the window level,
and the API call will always add it to that one now, since modal
handlers were not used in other levels.

The order used to be:
* window modal + keymap
* area modal + keymap
* region modal + keymap

Now it is:
* window modal
* region keymap
* area keymap
* window keymap

08e2da590f Particles cleanup, optimizations and some small new stuff.
New stuff
- Bending springs for hair dynamics.

Code cleanup & optimization
- Disabled reactor particles temporarily for cleanup, it's a clumsy system that will be replaced with something better.
- Removed child seams, something better will come here too :)
- Normal particle drawing data is now saved between redraws if the particles don't move between redraws.
	* For example rotating the 3d view is now realtime even with 1M particles.
- Many random values for particles now come from a lookup table making things much faster.
- Most accessed small point cache functions are now much faster as macros.
- Lot's of general code cleanup.
- Nothing big should have changed so if something doesn't work like it used to it's probably just a typo somewhere :)

69e919530e Keymaps now have a poll() function, rather than adding/removing
their handlers based on notifiers, which is simpler and more
reliable.

This fixes for example editmode or uv edit keymaps not working
when creating a new 3dview or image space.

e9587a89fa Hair dynamics with cloth simulation
- Hair dynamics have their own panel in particle settings with the settings from cloth panel that apply to hair.
- Basic internal friction force to quickly emulate self collisions and volume preservation. (Still very early code, but gives some idea of what's possible).
- Softbody simulation is no longer used for hair.
	* Old files with sb dynamics should just load the hair without dynamics so new dynamics can be applied.
	* Invasion of particles exceptions in sb code is finally over.
- Collisions with other objects are disabled for now and will be worked out in the future.

Other changes/fixes:
- Particle mode editing flag wasn't saved properly.
- Some old files with edited hair didn't load correctly.
- Disabled delete & specials menu in particle mode for non-hair editing.
- Fixed yet one more cloth & softbody pointcache update issue.
- Disconnect/connect hair now uses only the deformed mesh so it works correctly also for subsurfed emitters.
- Hair editing now updates correctly with a moving emitter.

c29780c12a * Temporary fix to get fluid sim (and fluid control) working properly (without animated parameters). This just fills the fluid sim animation channels with default values for now, but will need to be updated to new animation system. 2009-09-09 07:52:44 +00:00

08b8fc34cf Disconnect/connect hair:
- Moves hair from face-space to global space and back.
- Allows for editing of emitter mesh after hair combing.
- Disconnect hair before doing topology changing changes in mesh edit mode, connect after changes.
- Notes:
	* The closest location on emitter surface to the hair root is used to connect the hair.
	* Emitter deflection, sticky roots and add brush don't apply for disconnect hair in particle mode.
- Todo for future:
	* Copy disconnected hair from object to another (when 2.5 has proper copy operators again).
	* Possible automatic disconnect/connect with topology changing operations in mesh edit mode.
	
Other changes/fixes:
- Proper subtypes for some particle mode notifiers.
- Particle mode selections didn't draw correctly because of using lighting for the paths.

f09d605410 Some particles cleanup & fixes:
- Some big refresh issues with softbody & cloth point cache usage should now be fixed.
- Removed sticky objects from particles (better stuff will come back when I get to updating reactor particles).
- Some initial easy memory efficiency cleanup for ParticleData struct. The ultimate goal is to get particles less memory hungry -> more particles possible in single scene.
- Wrong path timing clamping caused hair particles to seem disappeared when changing between normal<->hair particles.
- "Calculate to current frame" in cache buttons baked instead of the intended function.
- Boids particle data is now a bit better organized.

Notifiers
---------

Various fixes for wrong use of notifiers, and some new notifiers
to make things a bit more clear and consistent, with two notable
changes:

* Geometry changes are now done with NC_GEOM, rather than
  NC_OBJECT|ND_GEOM_, so an object does need to be available.
* Space data now use NC_SPACE|ND_SPACE_*, instead of data
  notifiers or even NC_WINDOW in some cases. Note that NC_SPACE
  should only be used for notifying about changes in space data,
  we don't want to go back to allqueue(REDRAW..).

Depsgraph
---------

The dependency graph now has a different flush call:

DAG_object_flush_update(scene, ob, flag)
is replaced by:
DAG_id_flush_update(id, flag)

It still works basically the same, one difference is that it now
also accepts object data (e.g. Mesh), again to avoid requiring an
Object to be available. Other ID types will simply do nothing at
the moment.

Docs
----

I made some guidelines for how/when to do which kinds of updates
and notifiers. I can't specify totally exact how to make these
decisions, but these are basically the guidelines I use. So, new
and updated docs are here:

874d38eeb4 Point cache editing:
- Baked point caches for particles, cloth and softbody can now be edited in particle mode.
	* This overwrites the old cloth/sb cache editmode editing.
	* The type of editable system is chosen from a menu.
	* For particles the current particle system and it's current cache are used.
- Currently this only works for caches that are in memory, but some automatic conversion from disk to memory and back can be implemented later.
- All tools from hair editing can't be applied to point caches and are hidden in the tool panel and specials menu. Some functionality like subdividing paths can be later implemented in a slightly different way from how it works for hair.
- Code is not yet optimized for speed, so editing might be slow sometimes.

Known issues:
- Cloth doesn't update properly while in particle mode, due to the way cloth modifier currently works. Daniel can you check on this?
- As "particle mode" is not only for particles any more some other name would be in place?
- Better icons are needed for the path, point, and tip-modes as the current icons from mesh edit mode are quite misleading.
- Direct editing of point velocities is not yet implemented, but will be in the future.

Other changes:
- Hair editing doesn't require a "make editable" button press any more.
- Multiple caches in single particle system disables changing emission properties.
- Unified ui code for all point cache panels.
	* Defined in buttons_particle.py and imported for cloth, smoke & softbody.
- Proper disabling of properties in ui after baking point caches. (Daniel could you please make needed disable code for smoke panels as their functionality is not familiar to me.)
- Hair weight brush has been removed. Once hair dynamics is re-implemented I'll code a more useable alternative to the functionality.

Bug fixes:
- Unlinking particle settings crashed.
- Deleting the active object with particles in the scene crashed.
- Softbody didn't write point caches correctly on save.

b221c0e2e6 New point cache file format:
- HEADER (beginning of each file)
	* general header:
		+ 8 char: "BPHYSICS"
		+ 1 int: simulation type (same as PTCacheID->type)
	* custom header (same for sb, particles and cloth, but can be different for new dynamics)
		+ 1 int: totpoint (number of points)
		+ 1 int: data_types (bit flags for what the stored data is)
- DATA (directly after header)
	*totpoint times the data as specified in data_types flags

- simulation type
	soft body = 0, particles = 1, cloth = 2
- data types (more can be added easily when needed)
	data		flag		contains
	----------------------------------------
	index		(1<<0)		1 int	(index of current point)
	location	(1<<1)		3 float
	velocity	(1<<2)		3 float
	rotation	(1<<3)		4 float	(quaternion)
	avelocity 	(1<<4)		3 float	(used for particles)
	xconst		(1<<4)		3 float	(used for cloth)
	size		(1<<5)		1 float
	times		(1<<6)		3 float (birth, die & lifetime of particle)
	boids		(1<<7)		1 BoidData
	
Notes:
- Every frame is not nescessary since data is interpolated for the inbetween frames.
- For now every point is needed for every cached frame, the "index" data type is reserved for future usage.
- For loading external particle caches only "location" data is necessary, other needed values are determined from the given data.
- Non-dynamic data should be written into an info file if external usage is desired.
	* Info file is named as normal cache files, but with frame number 0;
	* "Non-dynamic" means data such as particle times.
	* Written automatically when baking to disk so basically a library of particle simulations should be possible.
- Old disk cache format is supported for reading, so pre 2.5 files shouldn't break. However old style memory cache (added during 2.5 development) is not supported. To keep memory cached simulations convert the cache to disk cache before svn update and save the blend.
- External sb and cloth caches should be perfectly possible, but due to lack of testing these are not yet enabled in ui.
	
Other changes:
- Multiple point caches per dynamics system.
	* In the future these will hopefully be nla editable etc, but for now things are simple and the current (selected) point cache is used.
	* Changing the amount of cached points (for example particle count) is allowed, but might not give correct results if multiple caches are present.
- Generalization of point cache baking etc operator & rna code.
- Comb brushing particle hair didn't work smoothly.

dc75023f6f Softbody now uses the new pointcache code.
Note: Rna access to softbody point cache is through softbody modifier although the point cache is in softbody settings. This is to make it similar to cloth.

Various fixes for painting, sculpting and particle edit, still
much to be done...

* Move RNA paint and sculpt structs into rna_sculpt_paint.c,
* Added Particle Edit RNA.
* Some tweaks to existing Paint RNA.

* Put texture paint and particle edit object in context.

* Fix some errors in the brush layout, properly doing None
  checks, fixing some wrong property identifiers.
* Added tool enum for texture paint and particle edit in panels.

* Allow editing brush textures in the texture buttons, still with
  a stupid toggle, ideas for how to make the connection better are
  welcome.

b4353a8443 Initial code for boids v2
Too many new features to list! But here are the biggies:
- Boids can move on air and/or land, or climb a goal object.
- Proper interaction with collision objects.
	* Closest collision object in negative z direction is considered as ground.
	* Other collision objects are obstacles and boids collide with them.
- Boid behavior rules are now added to a dynamic list.
	* Many new rules and many still not implemented.
	* Different rule evaluation modes (fuzzy, random, average).
- Only particle systems defined by per system "boid relations" are considered for simulation of that system.
	* This is in addition to the boids own system of course.
	* Relations define other systems as "neutral", "friend" or "enemy".
- All effectors now effect boid physics, not boid brains.
	* This allows forcing boids somewhere.
	* Exception to this is new "boid" effector, which defines boid predators (positive strength) and goals (negative strength).
	
Known issue:
- Boid health isn't yet stored in pointcache so simulations with "fight" rule are not be read from cache properly.
- Object/Group visualization object's animation is not played in "particle time". This is definately the wanted behavior, but isn't possible with the current state of dupliobject code.

Other new features:
- Particle systems can now be named separately from particle settings.
	* Default name for particle settings is now "ParticleSettings" instead of "PSys"
- Per particle system list of particle effector weights.
	* Enables different effection strengths for particles from different particle systems with without messing around with effector group setting.

Other code changes:
- KDTree now supports range search as it's needed for new boids.
- "Keyed particle targets" renamed as general "particle targets", as they're needed for boids too. (this might break some files saved with new keyed particles)

Bug fixes:
- Object & group visualizations didn't work.
- Interpolating pointcache didn't do rotation.

* Remove keyval.c, code is in wm_keymap.c already.
* Rename WM_operator_redo to WM_operator_props_popup.

and operators should be working correct, but most buttons are still
not actually there yet.

* Added near empty soft body, fluid, field and collision panels,
  tweaks to cloth panels.
* Fluid bake works, but without escape or showing any progress.
* Fluid/Softbody/Cloth/Collision can now be both added as modifiers
  or in the physics panels.
* Missing: fields & soft body for particles.
* Missing: proper updating softbodies, guess this code still needs
  updates after pointcache refactor?

912c2f440b Pointcache refresh part 2
* Based on what happens during simulation the cache is marked (also in cache panel, this could possibly be extended to 3d view as well) as:
	- exact (not marked)
	- outdated (simulation is not done completely with current settings)
	- non-exact (frames were skipped during simulation)

* The parameter "cache step" effects the number of frames between saved cache frames.
	- This can save a lot of memory (or disk space) if absolutely frame accurate simulation is not required.
	- Speeds up the "quick caching" very much.
	- Frames between cached frames are interpolated from the cached frames.
	- Current default value of 10 frames works nicely with up/down-arrows (skip 10 frames forwards/backwards on timeline), but can be changed if wanted.

* The caching can work in normal or "quick" mode:
	[Normal cache]
	- Basic: Calculate what even happens (settings change, big frame steps etc.) and cache results, if possible try to use "cache step" when saving cache frames.
	- Becomes non-exact: After larger than 1 frame steps.
	- Becomes outdated: After any change effecting the simulation other than frame steps.
	- Pros/cons: Freedom of doing anything and playing with particles, but exact results have to calculated from the beginning.

	[Quick cache]
	- Basic: Calculate simulation up to current frame automatically on changes with cache step sized jumps in simulation. With multiple "quick cached" simulations the smallest cache step is used.
	- Becomes non-exact: Always from frame 1 (unless cache step = 1).
	- Becomes outdated: Never.
	- Pros/cons: Not very accurate, but super fast!
	- Todo: Transform of any animated (non-autokeyed) object is locked! Probably needs some tinkering with anim sys overrides.

* The simulation can be run forwards or backwards even if it's cache is outdated or non-exact, the following rules apply in these situations:
	- step forwards (to unknown) -> simulate from last exact frame, store result
	- step backwards (to known) -> result is interpolated from existing frames, store result, clear cache forwards if current frame is after last exact frame

* "Calculate to current frame" runs the simulation from start to current frame with a frame steps of 1.
	- Baking does the same, but runs the simulation all the way to the end of simulation.
	- Rendering does this automatically if the simulation is outdated of non-exact, so all rendered simulations will always be updated and exact.
	
* Every cache panel also holds buttons to "Bake all dynamics", "Free all dynamics" and "Update all dynamics to current frame".

* Cloth simulation supports the new cache too.

ee9c260c38 2.5
- Added ND_SHADING notifier on linking materials, so it gives 
  refreshes in UI
- Removed reduntant debug prints

Crucial fixes in other code while checking warnings;
- Particle buttons were assigned to short, whilst data was int
- Filesel border select used float rect API, on an int rect.

e2b6cea3b9 2.5: Tool Settings
* Moved proportional edit, snap, autokey mode, and a few others
  from Scene to ToolSettings.
* RNA wrapped properties in ToolSettings for the UV editor:
  proportional edit, snap settings, selection modes.

6b15024f4a Pointcache refresh part 1:
* Particles support larger than 1 frame changes, bigger frame changes can result in inaccurate results, but it's super fast and you get a nice feeling of how the particles behave!
* "Cache to current frame" button calculates the exact result of particles at current frame.
* Current state of cache can be protected by making it a bake.
* Cache is now in memory by default, disk cache is an option.
* Only "viewport %" number of particles are calculated and cached in viewport, baking and rendering calculate all particles.
* Info on cached frames and memory usage given in ui.
* Support for exact "autocaching" of changes and large frame changes(disabled for now until exact place in event system is decided)
* "Continue physics" is probably deprecated after this and should be removed once sb & cloth use the new cache code.

Todo:
* Make softbody & cloth use the new cache things.

Other changes:
* Some cleanup of particle buttons.

51fbc95e8c RNA
* Added icon to property and enum property items. The latter is
  responsible for the large number of files changed.
* For RNA functions, added PROP_RNAPTR flag to ask for a PointerRNA
  as argument instead of a C pointer, instead of doing it implicitly
  with the AnyType type.

* Material: properly wrap diffuse/specular param variables, and
  rename some things for consistency.
* MaterialTextureSlot: added "enabled" property (ma->septex).
* Image: make animated property editable.
* Image Editor: make some things editable, notifiers, respect state.
* Context: fix issue with screen not being set as ID.

c8b4cf9206 2.50:
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD

Notes:
* Game and sequencer RNA, and sequencer header are now out of date
  a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
  not needed anymore.
  * Fix "duplicate strip" always increase the user count for ipo.
  * IPO pinning on sequencer strips was lost during Undo.

880c43ad5a First new particle code:
-Many things not yet working properly :)
-Experimental new (hopefully more logical) categorization of buttons, feedback on this is very welcome.
-Separate render & draw types, for example now there is actually a render option "halo" instead of all the different point draw types.
-Particles get recalculated only from buttons that actually change something that has to be recalculated, for example changing visualization doesn't reset particles any more.
-Boid physics buttons are still missing as I'm currently redoing the whole boids code.
-Point caching is still very wip, so baking is not possible for example, but I added a few cache baking flags for rna that were/will be needed for particle buttons logic.

b4d46e5ded UI: Layout Engine
* Buttons are now created first, and after that the layout is computed.
  This means the layout engine now works at button level, and makes it
  easier to write templates. Otherwise you had to store all info and
  create the buttons later.
* Added interface_templates.c as a separate file to put templates in.
  These can contain regular buttons, and can be put in a Free layout,
  which means you can specify manual coordinates, but still get nested
  correct inside other layouts.

* API was changed to allow better nesting. Previously items were added
  in the last added layout specifier, i.e. one level up in the layout
  hierarchy. This doesn't work well in always, so now when creating things
  like rows or columns it always returns a layout which you have to add
  the items in. All py scripts were updated to follow this.

* Computing the layout now goes in two passes, first estimating the
  required width/height of all nested layouts, and then in the second
  pass using the results of that to decide on the actual locations.

* Enum and array buttons now follow the direction of the layout, i.e.
  they are vertical or horizontal depending if they are in a column or row.
* Color properties now get a color picker, and only get the additional
  RGB sliders with Expand=True.
* File/directory string properties now get a button next to them for
  opening the file browse, though this is not implemented yet.
* Layout items can now be aligned, set align=True when creating a column,
  row, etc.
* Buttons now get a minimum width of one icon (avoids squashing icon
  buttons).

* Moved some more space variables into Style.

405cf80eb8 Big, big commit!!
1) Remove WITH_FREETYPE2 from code, so now blender always need freetype2
2) Remove the old bmfont
3) Remove ftfont and bFTGL library
4) Implement a new BLF_draw_default function for place that still need/use
   the old BMF api.

I try to update both, scons and cmake, but I only can test with make, so
hope all work fine.

MSVC is broken, but I don't have Windows, things to search and fix are
any reference to WITH_FREETYPE2, FTGL and BMFONT (take in care that
blenkernel also have a BKE_bmfont.h, this don't have anything to do with bmfont).
        Always have to link/include the freetype2 library
        Remove any reference to libbmfont
        Remove any reference to libftfont
        Remove any reference to libbftgl (or libbFTGL)

af02a0aa4e UI
* Headers and menus can now be created in python.
* Replaced the uiMenuItem functions to create menus with equivalent
  uiItem functions using a layout, removing duplicated code.
* More uiItem functions are now exposed to python.
* The text editor header, panels and one of its menus are now created
  in space_text.py.
* Buttons window data context icon new changes depending on active
  object.

Issues
* Icons are not wrapped yet, hardcoded ints at the moment.
* The ID browse template is unfinished.
