One important thing to keep in mind when using this feature is that you'll need to flip your textures vertically (both the GIMP and Photoshop DDS tools I've seen have support for this on export). This is a quirk in using a texture format originally made for DirectX/DirectDraw, and flipping the compressed data is a real headache. Another quick fix for this issue is to change the Y value for the Size in the Mapping panel in the Texture properties to -1 (default is 1).
Crash was caused by incorrect restoring OpenGL context due to some
weird bit operations used to indicate whether stuff like color arrays
is initialized resulting in some unpredictable results on different
platforms and drivers.
pass index, and a random number unique to the instance of the object.
This can be useful to give some variation to a single material assigned to
multiple instances, either manually controlled through the object index, based
on the object location, or randomized for each instance.

Added four new functions as shortcuts to creating GHashes that use the
standard ptr/str/int/pair hash and compare functions.
GHash *BLI_ghash_ptr_new(const char *info);
GHash *BLI_ghash_str_new(const char *info);
GHash *BLI_ghash_int_new(const char *info);
GHash *BLI_ghash_pair_new(const char *info);
Replaced almost all occurrences of BLI_ghash_new() with one of the
above functions.

Thanks to Brecht for reviewing!
* For VBO, add color to the VertexBufferFormat structure as three
unsigned bytes. Since mask elements are scalar the three color
components are identical to eachother, but the fixed-function OpenGL
pipeline requires colors to be either three or four components.
* For the same reason, multires VBO drawing now copies into the
VertexBufferFormat format as well.
* Regression: material colors will not show up correctly now, masks
colors are overriding. Not sure how to fix this nicely (would be
much easier to fix if drawing with vertex shaders.)
* Also, masks will only draw PBVH drawing, so only 'solid' drawing
will work correctly with masks.
* Changes to DerivedMesh interface: DMGridData has been removed,
getGridData() now returns an array of CCGElem pointers. Also added
getGridKey() to initialize a CCGKey (implemented only by
CCGDerivedMesh.)
* PBVH: added BLI_pbvh_get_grid_key().
* A lot of code is affected, but mainly is just replacing
DMGridData.co, DMGridData.no, and sizeof(DMGridData) with the
CCG_*_elem functions, removing the reliance on grid elements of
exactly six floats.
Any identifier that looks like an OpenGL identifier, but isn't, causes a false alarm by the glreport.py tool. Most of these were in comments so I just rephrased the comments. There were a couple of static functions/macros that were easy enough to rename. Only the glTexco and glIndex fields of the DMVertexAttribs struct was public and had non-local uses.
