This was broken in r.42515. In particular, rigs with Spline IK would break,
since they often use curves with hook modifiers controlling the control-points
of those curves.
A valid derivedmesh is needed for modifier_get_vgroup to work, and it wasn’t take care of when not in edit mode... Checked quickly the other deform modifiers, they all seem to handle this correctly.
- defvert_remove_index's index wasnt used anywhere, rename to defvert_remove_group
- defvert_add_to_group was local in MOD_weightvg_util.c, moved to deform.c and renamed to defvert_add_index_notest
real fix coming next...
- editmesh smooth & subdivide were using old mirror axis flag still.
- removed colbits from outliner and object code.
- commented some other parts of the code which access deprecated members and aren't called anywhere.
"The Blender Foundation also sells licenses for use in proprietary software under the Blender Licens"
also remove NaN references from files that have been added since blender went opensource.
- renamed BM_Compute_Face_Center() to BM_Compute_Face_CenterBounds() and added BM_Compute_Face_CenterMean() since there was code inline to find the mean center in transform.
- curve map insert point had a nested loop which used the same value to index different arrays.
- dynamic paint used ternary operator where both outcomes were the same.

Rationale: the name was confusing and not always used consistently, and this
map itself is not something that can be layered, rather the map can be used
as texture coordinates in some layered setup.
The original intent was to indicate this contained more than just UV's, but
the game engine settings have already been moved out, and apparently users
didn't really get this from the name anyway.
* Added some RNA tooltips, now that they are supported by dropdown lists.
* Fixed some RNA num properties UI steps.
* Fixed a memory leak in Proximity modifier (when dm of "target" object had to be created, it wasn’t freed...).
- UV's were not being calculated if there were too many VColor layers.
- precalc (omd->size * omd->spatial_size) was being called in a loop.
- use vector functions to avoid pointer indrections on each access which the compiler wont optimize - eg: och->ibufs_disp[f]->rect_float[4*(res_x*j + i) + 1]
- dont call abs() on ints (converts to double and back to int in this case).
also unrelated render buttons change. move saving options directly under the file path since these were easy to confuse with image format options like zbuf, ycc, preview.. etc.
The real reason for this crash is that ocean modifier (in generative setting) does not properly set the derived mesh face ORIGINDEX data to ORIGINDEX_NONE. With this the previous fixes are not necessary.
