* rna: memory leak fix for RNA_property_enum_value()
* rigify: generate root-most bones before children, this makes parenting to dynamically created bones work.

clear loc/size/rot wasnt updating child transformations, also removed some warnings

use tp_getset rather then checking the string on getattr for 'id_data' attribute

Sequencer unique names for duplicates & metas and name new strips when the operator doesnt set them.

Reenable disabled window switching shortcuts in 10.4 builds

Sequencer: Transform Strip updates (Durian wish)

Removed the Start/End Settings and the effect_fader from the sequencer transform strip.
The transform strip can now only be animated directly by keying the Scale X, Scale Y, Translate X, Translate Y and Rotation values.

Caveat:
The uniform scale re-uses the Scale X value, so when changing the animation on Scale X in the non-uniform scaling case, the uniform scaling will be affected too. This was done to not break files for Durian.

Note:
As much as I would have liked to clean up the TransformVars, it caused crashes of earlier versions of blender when opening the file.
The rna identifiers were also kept as to not break any existing animation on those keys.

Add include path to access gpu_buffers.h from pbvh.c.

*Missing notifier for Render Border.

MSVC projectfiles
* update for sculpt merge

NOTE: BLI_blenlib now uses functions in BL_gpu - I added the necessary include path to make it compile, but I'm not sure if this dependency shouldn't be avoided.

Sculpt:
* Temporary workaround for sculpt not working well with small polygons,
still seems to be some issues, but can at least paint now.
* Small optimization avoiding local function variable aliasing.

rigify
* optional default blend argument, use for better leg & arm defaults
* way to define arbitrary options for bones that can then be passed to the generator function, only used to set elbow target parent at the moment.

2.5 Sculpt Branch Merge

http://www.blender.org/development/release-logs/blender-250/sculpt-and-multiresolution/

Release logs are work in progress, also check missing items on that
page, there's still a few things that need work.

Quick summary of the changes:

* Use BVH for optimizing sculpt mode, doing only editing and updates
on nearby nodes.
* Memory reduction by use of CCG grids for subsurf, own undo stack,
no vertex-face map, no origindex, .. .
* Multithreading for sculpting, multires, and subsurf.
* Optional external file storage for multires displacements.
* Various tweaks to brush behavior.

Sculpt Branch:
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r25245:25315

UV Editor: added proportional edit buttons to the header.

Fix small mem leak in wm_window_get_size_ghost

* added an armature submenu where python defined armatures can go.
* bpy.utils.display_name(), which makes filenames and module names look nicer in menus eg... /home/me/foo_bar.py --> "Foo Bar"
* missing rna_path --> data_path renaming

Sculpt Branch:
* Added detection if VBO extension is supported.
* Redraw other 3d views after sculpting.
* Fix brush sometimes punching through mesh with very small polygons,
added an extra epsilon to the ray-triangle intersection.

COLLADA branch: patch from Jan Diederich for bump-map export via <extra> tag.

COLLADA branch: small code clean-ups in bone anim export. Correct bone anim export is to be done yet.
