globbing vs explicit is discussed here.

Practical implications are:
- developers need to keep CMakeLists.txt files up to date.
- Users wont get strange linking errors if they build after a file is added, since CMake detects CMakeLists.txt is modified and automatically reconfigure.
Based on patch from Alexander Kuznetsov. Own changes:
- Keyframes in timelime depends on active object, so timelime better be
listeing to ND_OB_ACTIVE notifier rather than ND_OB_SELECT
- When scene is changing in this operator NC_WINDOW notifier would be send
and the whole interface would be redrawed, so no need in ND_OB_ACTIVE in
this case
* The existence of cached frames was checked each frame causing hundreds of disk operations per frame update.
* Pointcache now keeps an updated array of the cached frames for fast "frame exists in cache" queries.
* This fix also speeds up some other pointcache operations nicely.
This happened/was most noticeable when clicking on a bone of an armature in posemode but not active (i.e. some object other than the armature is active when trying to select the bone).
* Added ND_FRAME_RANGE to the header listener, changing frame range in Properties Window didn't update it in the timeline, reported by Hardworker in IRC. Thanks!
* Main Area Listener doesn't listen to all NC_SCENE Notifiers now, only selected ND Notifiers, like the header does. This is more efficient. If there is a reason to let it listen to all NC_SCENE notifiers, please tell me. :)
This started off doing pointcache debugging but it's also very useful for users too.
Previously it was very hard to see the state of the system when you're working caches
such as physics point cache - is it baked? which frames are cached? is it out of date?
Now, for better feedback, cached frames are drawn for the active object at the bottom
of the timeline - a semitransparent area shows the entire cache extents, and more
solid blocks on top show the frames that are cached. Darker versions indicate it's
using a disk cache.
It can be disabled in general in the timeline View -> Caches menu, or by each individual
system that can be shown.
There's still a bit to do on this, behaviour needs to be clarified still eg. deciding what
shows when it's out of date, or when it's been played back but not cached, etc. etc.
Part of this is due to a lack of definition in the point cache system itself, so we should
try and clean up/clarify this behaviour and what it means to users, at the same time.
Also would be interested in extending this to other caches such as fluid cache,
sequencer memory cache etc. in the future, too.
Only source/blender/editors/ dir, should not give errors on different platforms
Only removing: UI_*.h, ED_*.h, WM_*.h, DNA_*.h, IMB_*.h, RNA_*.h, PIL_*.h
Blender too now! :)
** Drag works as follows:
- drag-able items are defined by the standard interface ui toolkit
- each button can get this feature, via uiButSetDragXXX(but, ...).
There are calls to define drag-able images, ID blocks, RNA paths,
file paths, and so on. By default you drag an icon, exceptionally
an ImBuf
- Drag items are registered centrally in the WM, it allows more drag
items simultaneous too, but not implemented
** Drop works as follows:
- On mouse release, and if drag items exist in the WM, it converts
the mouse event to an EVT_DROP type. This event then gets the full
drag info as customdata
- drop regions are defined with WM_dropbox_add(), similar to keymaps
you can make a "drop map" this way, which become 'drop map handlers'
in the queues.
- next to that the UI kit handles some common button types (like
accepting ID or names) to be catching a drop event too.
- Every "drop box" has two callbacks:
- poll() = check if the event drag data is relevant for this box
- copy() = fill in custom properties in the dropbox to initialize
an operator
- The dropbox handler then calls its standard Operator with its
dropbox properties.
** Currently implemented
Drag items:
- ID icons in browse buttons
- ID icons in context menu of properties region
- ID icons in outliner and rna viewer
- FileBrowser icons
- FileBrowser preview images
Drag-able icons are subtly visualized by making them brighter a bit
on mouse-over. In case the icon is a button or UI element too (most
cases), the drag-able feature will make the item react to
mouse-release instead of mouse-press.
Drop options:
- UI buttons: ID and text buttons (paste name)
- View3d: Object ID drop copies object
- View3d: Material ID drop assigns to object under cursor
- View3d: Image ID drop assigns to object UV texture under cursor
- Sequencer: Path drop will add either Image or Movie strip
- Image window: Path drop will open image
** Drag and drop Notes:
- Dropping into another Blender window (from same application) works
too. I've added code that passes on mousemoves and clicks to other
windows, without activating them though. This does make using multi-window
Blender a bit friendler.
- Dropping a file path to an image, is not the same as dropping an
Image ID... keep this in mind. Sequencer for example wants paths to
be dropped, textures in 3d window wants an Image ID.
- Although drop boxes could be defined via Python, I suggest they're
part of the UI and editor design (= how we want an editor to work), and
not default offered configurable like keymaps.
- At the moment only one item can be dragged at a time. This is for
several reasons.... For one, Blender doesn't have a well defined
uniform way to define "what is selected" (files, outliner items, etc).
Secondly there's potential conflicts on what todo when you drop mixed
drag sets on spots. All undefined stuff... nice for later.
- Example to bypass the above: a collection of images that form a strip,
should be represented in filewindow as a single sequence anyway.
This then will fit well and gets handled neatly by design.
- Another option to check is to allow multiple options per drop... it
could show the operator as a sort of menu, allowing arrow or scrollwheel
to choose. For time being I'd prefer to try to design a singular drop
though, just offer only one drop action per data type on given spots.
- What does work already, but a tad slow, is to use a function that
detects an object (type) under cursor, so a drag item's option can be
further refined (like drop object on object = parent). (disabled)
** More notes
- Added saving for Region layouts (like split points for toolbar)
- Label buttons now handle mouse over
- File list: added full path entry for drop feature.
- Filesel bugfix: wm_operator_exec() got called there and fully handled,
while WM event code tried same. Added new OPERATOR_HANDLED flag for this.
Maybe python needs it too?
- Cocoa: added window move event, so multi-win setups work OK (didnt save).
- Interface_handlers.c: removed win->active
- Severe area copy bug: area handlers were not set to NULL
- Filesel bugfix: next/prev folder list was not copied on area copies
** Leftover todos
- Cocoa windows seem to hang on cases still... needs check
- Cocoa 'draw overlap' swap doesn't work
- Cocoa window loses focus permanently on using Spotlight
(for these reasons, makefile building has Carbon as default atm)
- ListView templates in UI cannot become dragged yet, needs review...
it consists of two overlapping UI elements, preventing handling icon clicks.
- There's already Ghost library code to handle dropping from OS
into Blender window. I've noticed this code is unfinished for Macs, but
seems to be complete for Windows. Needs test... currently, an external
drop event will print in console when succesfully delivered to Blender's WM.
Made preview range be turned on/off using a proper flag instead of just relying on checking for start-frame = 0. It is no longer satisfactory to do that since we can have negative frame numbers, and also having it as a proper flag means that the range can be toggled on/off non-destructively.
When 'Only Selected' is ON, or the Active Object is in PoseMode, only the keyframes for the active Object are drawn (*).
Otherwise, the keyframes for the scene (sequence+nodes+world), and the selected Objects (including the Active Object) are drawn.
(*) I've also made some changes here to try and get only the selected bones showing here, but some further changes are still needed for that to be able to work.

Also, fixed bug in makesrna caused by missing newlines for error prints. This resulted in all error-output from makesrna appearing on a single line.
* Moved 'change shortcut' (previously directly RMB on menu items) to a context-menu item, and added Remove Shortcut and Add Shortcut. This is all available now in a RMB context menu for operator buttons and menu entries.
* Renamed a bunch of key maps to be consistent with UI names, and human-readable. Since these key map names are now being directly used in the UI for people to find things, they should be understandable and in plain language.
This renaming may break some older saved key map setups - though previously saved .b25.blends should convert over ok. Exported .py files may need some find/replacing - in this commit check the changes in resources.c to see what's changed.
* Made the TimeLine current frame indicator get drawn using the standard frame-indicator code. Also, it is now possible to show the frame indicator box beside the line as in the other animation editors, although this is disabled in the timeline due to the closeness of the frame number field.
* Removed some old (unnecessary) code
-> "Continue Physics" option in TimeLine, which is now obsolete with the current physics options. Feel free to restore if this is not the case.
-> Already commented out hacks to create "speed ipo" for curves. There are easy alternatives that are better integrated.
-> Unused init/exit callbacks for scrubbing time, since those were only used to set an obsolete flag for timeline drawing that is now used for the indicator.
* Switched long-keyframe optimisation code to use constants instead of some magic numbers + fancy trickery...
This contains two entries - one which calls the region flip operator, and one which calls the maxmize area operator.
Unfortunately, there seem to be some context issues which are causing the wrong region to get activated for use by the region flipping, meaning that nothing happens.
Also, fixed own typo in 3d-view header/menu code...
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.
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.
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:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/NotifiersUpdateshttp://wiki.blender.org/index.php/BlenderDev/Blender2.5/DataNotifiers
* Use scene->r.audio instead of scene->audio everywhere, was using both still.
* Fix time_top_left_3dwindow link error, not sure why this happens, somehow
with scons building it seems that files (like time_header.c) wich are not
called from the same .a module get stripped?
* Finally the header and menus are done via python.
* Added RNA for sync audio.
Note: This is just a basic working version in python. It needs more work and some layout changes.
Joshua: Feel free to adjust this further :)
* Move sound_init to make sure it gets called everytime user
preferences is reloaded.
* Merged sound_reinit and sound_init. One used user preferences
while the other did not, don't see the point of this, so just
made it always use user preferences now.
* Timeline header audio sync option now controls scene flag
rather than timeline flag. Since it uses the same playback
operator now, there is no distinction anymore.
* Added boolean property sync to animation play operator, to sync
with audio or not. Uses scene setting if property is not set.
* Playback stop button in info header now calls operator, so sounds
stop playing too.
* Fixed padding for Graph Editor visibility toggles
* Reverted many of the tweaks to Timeline UI for now (for the reasons outlined in earlier mail)
* NLA Editor now (mostly) uses the new channel-drawing API
-Made the 'PR' button not align itself to the start/end frame fields, as this makes for a nicer visual rounding of those two numbers.
-Made current frame indicator longer, to allow for display of higher frame numbers
-Removed the auto-keyframe dropdown menu. This exists as a preference, and doesn't need to take up space here. This is not something you're likely to change much after all.
-Made the keying sets menu stay put in the UI. It was moving about depending on what options are selected to the left of it. This sort of moving around should be avoided as much as possible.
-Swapped Add/Delete keyframe buttons. It's more intuitive to have the add key button first.
