Main Feature:
* It is now possible to choose which AnimData block is the 'active' one for editing, and/or select them too. AnimData blocks are generally the dark blue and lighter-blue expanders (i.e. Scene, Object, Camera, Lamp, Curve, Armature, etc.)
* Objects are no longer selected/deselected when AKEY is used to toggle selection of channels. This was getting a bit annoying.
* Following on from selection of AnimData blocks, it is now possible to select/make active an AnimData block in the animation editors, and change the active action for that block via the 'Animation Data' panel in NLA Editor's properties region.
--> Be aware that user-counts are not totally handled correctly there yet, so some funky behaviour might be seen...
--> It is possible to assign a new action, or to assign an existing one, allowing to switch between actions as in the past with Actions/IPO Editors...
Other tweaks:
* Some code tweaks towards making the 'Euler Filter' feature for Graph Editor working sometime soon
* Added some backend code for snapping the values of keyframes to a single value. Still need to work out some UI for it though.
* Shuffled the code for ACT_OT_new() around, and removed the poll() callback so that it worked in NLA too.
* Fixed some more notifier bugs with deleting bones and a few other editmode operations for Armatures.
* All the selected F-Curves will get the same type of F-Modifier added.
* The button in the properties region will still only added the F-Modifier to the active F-Curve though
* For now, there must be an active F-Curve in either case, otherwise the poll() callback fails.
* Deselect all now selects/deselects F-Curves too
* Tangents of unselected F-Curves now draw 'faded' like the curves they belong to. This experimental change is quite subtle, but can be made stronger still if people want.
* Cleaned up some old comments in the code too...
* Updating Preview Range settings results in correct updates for Animation Editors
* Compositing nodes now correctly animate when the values were set by IKEY/RMB on suitable node parameters. Beware that these nodes are not relinkable node-trees, hence the standard code not working.
* Ctrl-P to parent objects to bones now works in Pose Mode too. I needed to add a special keymap entry for this, though I thought this would have been better to be automatically inherited/present from Object keymap already?
* Ctrl-P -> Parent to Bone option now works correctly again. 1.5 lines of code missing here...
* Breakdowns tool now shows custom cursor during 'modal' phase so that it's not that confusing what's going on.
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.
* Removed some legacy code which is not needed anymore now.
* Move some test_*poin_but functions to logic space code,
since that's the only place using it still.
* uiIconFromID now uses RNA info to lookup the icon, to avoid
code duplication, and means it works for more ID types.
#19345: can't get out of grayed out pointer field.
#19342: item_pointerR fields can't be cleared with one item.
#19341: fix hanging tooltips when manipulating regions.
#19339: context panel still allowed tabbing, but it has no header.
#19334: editing SSS settings crashed previewrender.
#19330: object mode could not be switched on from the header menu.
* Mesh Deform modifier now correctly shows Bind/Unbind buttons. Previously, only Bind got shown...
* Selecting keyframes in the Graph Editor using Border Select now allows the keyframes to be editable afterwards. Previously, the curves weren't getting selected afterwards, therefore, the poll operators would skip those curves.
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
* DopeSheet + Graph Editor - 'Sample Keyframes' option now tags newly created keyframes as being breakdowns. Also moved reduced the code duplication here by moving the core code for this to the animation module.
* Keyframing (Standard/Auto) - Added proper 'replace' option
Keyframes can now be rekeyed non-destructively when the INSERTKEY_REPLACE flag is provided to the keyframing API functions, since this option will make sure that only the values of the handles get altered.
For the Auto-Keyframing 'Replace/Edit Keys' option, this means that it truly works as it describes now, since it will now only replace the values of the keyframes on the current frame, and won't create new keyframes in the process or destroy the tangents already created for those keys.
For things like the sliders in animation editors, keyframes changing the value won't destroy existing tangents.
It is now possible to tag certain keyframes as being 'breakdowns' in the DopeSheet. Breakdown keyframes are drawn as slightly smaller blue diamonds.
Simply select the relevant keyframes and use the RKEY hotkey (or from the menus, Key->Keyframe Type) to choose between tagging the keyframe as a 'proper' keyframe and a 'breakdown' keyframe.
Notes:
* Please note that this feature does not currently imply anything about breakdowns moving around keyframes or behaving any differently from any other type of keyframe
* In future, if there is any such need, more keyframe types could be added, though this is not really likely at all
The 'Show Sliders' option for DopeSheet and Graph Editors now works again. When this option is enabled (it is disabled by default), a slider (or combobox) is shown beside the mute/lock toggles for F-Curves. Editing the slider will result in a new keyframe being added on the current frame.
So, for all the (ex)-Maya animators out there, you can now animate in a channelbox-like way. :)
Also in this commit:
* Fixed some warnings in modifier.c from previous commits there
* Fixed some refresh problems with DopeSheet channel list (which were only obvious after adding back the sliders)
* Removed the old/unrestored and nasty slider code used in the past by the Action Editor only.
when passing properties=True as argument.
Other changes:
* uiItemR, uiItemFullR, uiItemFullO now accept a flag argument rather
than multiple different "boolean" arguments, but still exposed as
booleans to python.
* Fix RNA to support setting PROP_RNAPTR for return values.
* Fix header menu spacing bug, and make it consistent for all headers.
* For consistency, always put menus first in the header, then any enums
to switch the type of data displayed.
* Node editor header ported to python layout. Still quite a few
operators missing to make the menus complete.
* RNA wrapped node editor, and added use_nodes property to material
and scene.
Alpha for icons wasn't getting set correctly in animation editors anymore. This commit should fix the issues there, though the scrollbars still have a few minor issues still too.
Also, NLA strips with repeats now have the repeat indicators drawn only 80% or so of the height, making it easier to distinguish between strips with repeats and bunches of strips.
Now the mute/protect/expand/etc. toggles are drawn using UI widgets. This means that special event handling code to determine when they were clicked on is no longer needed, and also means that there can now be tooltips for these items too.
Also, added visibility toggles for ID-block expanders, which will cause all the F-Curves in the linked datablock to not get drawn. The backend filtering code to make this work will come later...
* 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
Finally started refactoring the drawing code for animation editors so that all the drawing (of the channels/names list) is done using standardised code for all the editors.
A little specialised system for this has been made, and is now used for DopeSheet and Graph Editor drawing. This should make it easier to add new channel types with less effort.
Protect/mute toggles are now always clamped to the right-hand edge of the channels list. So you can now make the list wider to view longer names fully. However, since the mouse-handling hasn't been fixed yet, this won't always work.
TODOs:
* make mouse-click handling code use this system too, simplifying things to 1-2 lines of code there. Maybe this could be made to use UI widgets instead at a later date?
* NLA still needs to be ported to this system
* Tools such as set handle type, etc. were not being called correctly from the menus. There were missing operator-context calls to make sure that the invoke methods would get skipped.
* Hack for loading old files - buttons region for Graph Editor now gets added. Dunno why this didn't work automatically as for NLA despite the two having the same code.
* Animated ShapeKey F-Curves/Drivers are now visible in the Animation Editors.
* As a result of this, the old 'ShapeKeys' mode (which would display all the shapekey channels, even if they had no keyframes yet) in the DopeSheet, no longer works for now. However, it would have been of no use as no sliders were shown anyway.
* Drivers which depended on the rotation of bones now work again. These now point to the right RNA properties, and get some extra 'time' corrections (for degrees -> radians change).
* When resizing the window, the top position is now preserved,
instead of the center position.
* Fix zoom level not being preserved in various cases, when
changing both with and height. This replaces some earlier code
which did this at screen level but wasn't very reliable.
* Different tabs now each preserve their own scroll.
* When switching between tabs, it now scrolls to show as many
buttons as possible, instead of possibly showing empty space.
There is a trade-off here between doing that keeping the
buttons in the same place, no ideal solution exists I think.
* Change zooming in/out to be symmetric, for example doing
numpad + then - did not give the original zoom level back.
* Added some calls to avoid hanging tooltips when manipulating
the view.
Internals:
* Added V2D_KEEPOFS_X and V2D_KEEPOFS_Y to keep the top/bottom
rather than the center.
* Renamed V2D_KEEPZOOM to V2D_LIMITZOOM (seems more appropriate),
and make V2D_KEEPZOOM preserve the zoom level.
* Cleaned up some parts of the code that were unused/could be done a bit nicer
* Added a new option for only showing the keyframes of the selected F-Curves in the Graph Editor, as another way of reducing the clutter.
* Split strips now uses the current frame as the splitting-point for selected strips if the current frame falls within in the bounds of the strip. Otherwise, the code defaults to splitting by the midpoints of the strips.
* Time-range for Graph Editor is saner now when there is only a single keyframe or none at all.
DopeSheet and Graph Editor operators were missing these, since many of these operators were written before that field was added.
NLA Editor's operators already have them.

Highlights of the new NLA System (and related Animation System changes):
* NLA Data is stored in AnimData alongside Action and Drivers. The NLA stack is evaluated before the Action, with the Action always overriding the results of the stack.
* NLA Data is arranged in 'Tracks', which act like PhotoShop layers. These can be muted, protected, and/or made to be played back by themselves
* Within each track, there can be multiple 'Strips'. There are 3 types of strip -> Action Clip (references some action), Transition (blends between the endpoints of two strips), and Meta (container for several strips that occur sequentially)
* FModifiers can be applied to strips, and strips can have animated influence/time controls. Playback for strips can also be backwards now!
* Playback can now go in forward and backwards directions.
* Animation Editors have been polished (unfinished features added, existing features cleaned up and made more consistent)
Notes for BuildSystem Maintainers:
* Only scons has been actively tested. Makefiles should work fine.
* MSVC ProjectFiles are broken due to the very way they work.
* CMake status unknown...
Other notes:
* Hopefully I haven't made any mistakes while doing the merge. More files than expected were showing some weird conflicts, so you may have some broken code...
* Not all old files (with NLA) data load exactly the same anymore. However, the bulk of the files out there should be ok (I hope)
I've gone through all the Animation Editor operators, making sure they send appropriate notifiers, and that these notifiers are handled.
* Added a separate category for animation-related notifiers, since the old-style ones attached to specific datatypes only was turning out to be not too feasible.
* For now, the focus has been on making sure that all Animation Editors update when there have been any potentially suitable changes at all. Later on, we can filter these more carefully to only take the ones we really need (for optimisation purposes)
* Rename BIF_transform/retopo.h to ED_transform/retopo.h
for consistency.
* Move MESH_OT_duplicate_add to editmesh_add.c.
* Remove some code from BIF_gl.h which is not needed there
anymore.
* When influence/time for NLA-strips are animated, settings in the other panels which used to control these are now greyed out to show that they won't have any impact over the result.
* NKey panel for Graph Editor now opens on Right-Hand Side, just like for NLA Editor. The small sub-region above the Channels region was too troublesome to work with.
This commit is quite experimental, and might have to be reverted, but in quite a few places, the cleanups from this commit were already necessary.
* I've left most of the image-handling functions alone, since I'm not sure how well they cope with negative indices.
* Start/End frames cannot be negative for now... any specific reasons why they should be negative?
Groups (the Action variety) can now be muted, and also be set to not be drawn in the Graph Editor. These settings get applied to all the F-Curves within the group, overriding any settings individual F-Curves might have, allowing users to quickly mute or hide groups of curves without having to go through clicking on all of them.
Also, added a flag that can be used to set the curve visiblity on AnimData level too. This will be enabled in a future commit.
* Made NLA Editing functions more aware of transitions.
- A transition can only be added between a pair of action-clips. Previous, two transitions could be added next to each other, which has undefined behaviour
- Deleting a strip with transition(s) on either side will remove the transitions too. Feedback welcome on this
- The 'type' setting for NLA-Strips is no longer editable. This was dangerous as it could result in transitions with undefined behaviour (though nothing would happen).
* Menus for adding F-Modifiers now only show relevant modifiers (i.e. 'Invalid' is not included in the list, and 'Cycles' doesn't need to be shown for NLA since we've got repeat)
* Function Generator and Noise F-Modifiers now have complete GUI's. A few settings were missed during the porting process.
* F-Modifier buttons now have their source-ID's included in the RNA Pointers used. This didn't get them animateable directly, but is a step closer.
Cleanup of scroller drawing in 2D windows.
Before:

After:
http://download.blender.org/institute/rt12.jpg
Will add 'zoom' widget circles later, as mockupped here:
http://www.reynish.com/files/blender25/fcurve_scrollbar.png
Also note the scale values are inside scroller; drawing it
on top conflicts with current frame item and markers.
Currently scroller disappear entirely when view is total.
For Joshua:
To make sliders behave nicely, the boundbox (v2d->tot) has to
be refreshed on each change. I've added it in graph drawing
now, but it could be notifier based I guess... not sure what
the correct anim api call would be. Can discuss tomorrow!
On todo:
Layout config hints so people can make scroller positions swap.
* Most of the F-Modifiers have been ported to use the layout engine + RNA for drawing their buttons now. This plays much nicer with various button-layouts.
--> As a nice demo, try adding a Noise Modifier to a NLA-strip, and change the 'size' setting to about 2 to see some effects.
* Generator and Envelope modifiers haven't been ported yet since they're quite complex (requiring more time + energy), and as such, have been made to have some temporary error prints instead. Will check on this tomorrow.
* Finished/cleaned up the RNA-wrapping of most FModifiers.
TODO's (help requested... Brecht?):
Generator modifier's UI cannot be wrapped yet using the layout engine (though I might try using the old system only), as I'm having some trouble wrapping the coefficients array for this (see rna_fcurve.c - rna_def_fmodifier_generator())
* Using the Ctrl-Shift-M hotkey, F-Modifiers can be added to all the selected strips.
* F-Modifiers can also be added/tweaked from the NLA N-Key properties. The UI now uses the same code as for the graph editor ones.
The UI drawing here is currently messed up from the NLA side, since it seems combining normal layout stuff and old-style uiBlocks doesn't seem to work too well (BUT! the buttons are at least functional).
Next up, I'll need to recode the buttons panel for the Graph Editor so that all of the drawing can be migrated over to use the new layout engine.
* F-Modifier API is now in its own file in blenkernel
* Renamed and refactored these so that they're no dependent on F-Curves, since all they really used was the fcu->modifiers list
* Added missing license blocks to a few files
* F-Modifier UI drawing/handling is now defined in a separate file so that it will be more suitable for inclusion into the NLA Editor's buttons.
* Started removing F-Curve dependence from the modifier drawing code, which wasn't strictly necessary
* Fixed F-Curve RNA wrapping to correctly use FPoints instead of the bulkier BPoints. Although nobody was likely to have encountered bugs here yet, this would almost certainly have contributed to some segfaults/data corruption along the track.
Started cleaning up FModifiers in preparation for allowing them to be used on NLA Strips.
This commit separates the 'Built-in Function' mode for the Generator modifier out into its own modifier, since it was being quite frequently used (and the RNA wrapping for this used to be quite hackish).
BACKWARDS COMPATABILITY WARNING:
Old files with FModifiers saved (i.e. old 2.5 files, but not any others) will not load correctly as a result of these changes (the wrong modifiers will be shown). I've decided that there are not likely to be many files affected by this yet, but doing this will result in a much nicer modifiers-define list in the long run.
For now, some of these polls may be a bit too restrictive, but at least we have some unified+cleaned bases to work from now (instead of relying on the generic ED_operator_area_active).
