Merging r38265 through r38295 from trunk into soc-2011-tomato

make python3.3 compatible, __class__ is no longer in the class methods namespace.

Fix for [#27398] Particle systems with animated groups render incorrectly in viewport
* Hmph.. depsgraph and group duplication == illogical.

Fix for [#27293] Group Instance of particle system is rendered wrong
* Silly mul_m4_v3 had turned into a mul_m4_v4 at some point!

-OpenEXR fixed so enabling if user has enabled
-Added Iex to lib list, was causing link time errors

run WM_exit(C) when blender as a python module exits

Fix #27926: autokey not working with auto IK, broke this with an earlier bugfix.

Camera tracking integration
===========================

- Fixed sub-pixel precision error when sliding markers.
- Made sliding areas smaller.
- Remove "Debug" menu,
- pep8 cleanup.

Fix for [#27289] Hair: Render Option - Object does not point objects to end of "hair path"
* Objects are now always rotated in the directions of the hair paths
* Secondary fix: particle size wasn't updated for hair particles, so dupliobject size couldn't be change after the hair was edited

fix for various python bugs and remove unused var.

Fix for [#26873] Animated displacement modifier on an object doesn't work with hair particle objects
* Noise is now considered an animated texture as it changes with every frame
* Converted a few places in particles code to use the particle system's own random table instead of BLI_frand.

Merge with trunk r38281

Dynamic Paint:
* Proximity brush color ramp should now work properly with any type of proximity brush.
* Dynamic Paint operators (adding surfaces, baking, etc.) now affect right object even when ui is pinned to a non-selected object.
* Fixed proximity falloff for vertex weight surfaces.
* Fixed possible color issue with low alpha brushes.
* Fixed a compiler warning.

cleanup for python scripts - unused vars and imports

Bug Fix.

Some optimizations and coding style improvements across the retargeting and constraint scripts

Camera tracking integration
===========================

- Added option to keep area equal width and height
when sliding it by mouse. Use "Control" button for this.
- Do now show sliding zones for disabled markers.

fix for NULL pointer usages

Camera tracking integration
===========================
