* DNA_cloth_types.h, patch by Roelf de Kock. The gravity[3] member
is not being parsed correct by makesdna.c and will give issues
even when trying to fix it. Worked around it for now in RNA by
wrapping it manually, but this should really be fixed in the DNA
genetics code, added a comment about it in DNA_cloth_types.h.
* Handle vertex groups and uv layers more consistent now. They are
all exposed as strings now. Reason is that indices don't really
say much, and a direct pointer is not always possible because for
example a uv layer in a material can be used for multiple objects
and so there is no single pointer. In python it is not too hard
to use either since the strings works as a key for lookups.
For the user interface we can later think of some method to
generate popup menus in a way that works for vertex groups,
uv layers, bones etc.
* This also fixes the XXX's in rna_modifier.c, I think that can be
marked done.
the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:
* GLSL support in the viewport and game engine, enable in the game
menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.
* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
An extra texture slot shows up once the last slot is used.
* Memory limit for undo, not enabled by default yet because it
needs the .B.blend to be changed.
* Multiple undo for image painting.
* An offset for dupligroups, so not all objects in a group have to
be at the origin.
