* fix for point density - particle systems weren't being
deformed by lattices

missing undo for vgroup operations, countall was running twice from select/deselect and DAG_object_flush_update isnt needed for changed selections.

fix for [#17878] Scripts operating on blender objects don't clear memory after a crash
This is an interesting bug since it is likely the cause of many other suspicious python crashes in blender.

sys.last_traceback would store references to PyObjects at the point of the crash.
it would only free these when sys.last_traceback was set again or on exit.

This caused many crashes in the BGE while testing since python would end up freeing invalid game objects -
When running scripts with errors, Blender would crash every 2-5 runs - in my test just now it crashed after 4 trys.

It could also segfault blender, when (for eg) you run a script that has objects referenced. then load a new file and run another script that raises an error.
In this case all the invalid Blender-Object's user counts would be decremented, even though none of the pointers were still valid.

Tweaked rendering inside a volume to always return alpha 1.0.
This fixes an issue which darkened the render from inside a
volume with sky or premul on. Still need to find a good way to
get an alpha value back into the shader (for compositing etc)
without getting the render distorted by premul.

Point Density:

Replaced 'Sharp' falloff with 'Soft'. This falloff type has
a variable softness, and can get some quite smooth results.
It can be useful to get smooth transitions in density when
you're using particles on a large scale:

Also removed 'angular velocity' turbulence source - it
wasn't doing anything useful atm

fix for a compile error with msvc

* Fixed a crash with using light cache on a plane (which doesn't really make sense, but shouldn't crash at least)

add a way for external scripts to call X3D/VRML importer and deal with unknown node types.

Patch from Timothy Baldridge
* add irix6 to GHOST windowing system (same as linux2 et al)
* fix faulty return lines in shrinkwrap.c

Fixed Subdivision method (subdivide in a set number of bones).

Subdivision method cleanup (reuse more code)

Auto Roll:

Bone roll to face the screen on painted strokes.

Draw subdivision preview for quick strokes and selected strokes (those that would be converted).

Preview can be slightly off for quick strokes since subdivision will be affected by stroke smoothing applied only when a continuous stroke is finished.

Fix for bug #17881: with SSS disabled, SSS materials didn't
render textures, related to other recent bugfix for baking.

* improvement for CSizeof
- instead of fiddling around with strings, just compare pointers. (It's a good thing we have ideasman_42)

more python 2.3 compat, should be the last of it.

Duplicating bones in EditMode didn't set the custom-shape and bone-groups too.

Bugfix:

"Warning: binarysearch_bezt_index encountered invalid array" errors were being displayed in the console. Was caused by 3d-view show-keyframe for infostring stuff, when an IPO being checked had no keyframes.

* Add some missing docu for Blender.Types
* Fix potential crash in CSizeof()

* reimplemented some things, hopefully may fix some problems zanqdo was having

Bugfixes:

- Adding constraint using button in panel still didn't update Armature Editing buttons properly.
- Minor code tidying of earlier bugfix for armatures
- 'For Transform' option for Limit constraints is now only taken into account for constraints that are enabled.
