Another possible fix for #29301: issue with BVH intersection, reorder code a
bit so that it's more symmetric and resulting float ops are compiled the same
way. Otherwise extended float precision being used in one place and not the
other can make comparisons fail.

Remove MTEX_BUMP_FLIPPED flag which was added temporary when white/black colors
for bump maps were toggled.

Update space text's viewlines even if no text selected. It's needed for
proper positioning to cursor when switching to text datablock in case
there was no datablock opened in text editor.

cellalloc wasnt being used for deform weights when it should have been, checked all uses of MDeformWeight's to make sure this is ok.

Forcing multires update when doing multires baking

Prevents issues with missed strokes baked into image when baking from sculpt mode.

svn merge ^/trunk/blender -r42290:42292

dynamic paint
- replace inline code with existig defvert_find_index()
- use madd_v3_v3fl() func and remove redundant normalize call.

svn merge ^/trunk/blender -r42261:42290

fix for parenting bug introduced by own commit r42273, adding dummy object didnt initialize delta vectors.
also remove redundant NULL initializers, where the value is initialized immediately after.

use consistent naming for deform.c, also moved defvert_remove_index into deform.c, was local in modifier code.

fix [#29450] Mirror Vertex Groups issue

remove wrong solidify & draw changes i had checked in here and had also proposed for trunk, because the problem was fixed differently in trunk.

#-This line, and those below, will be ignored--

M source/blender/modifiers/intern/MOD_solidify.c
M source/blender/blenkernel/intern/cdderivedmesh.c

fix [#29462] libraries.load can't have link=False when relative=True

was doing an unnecessary (and incorrect) library lookup.

Deduplicate code used for drawing text information at the top of space region.

Rename Movie to Movie Clip source for background image

fix [#29459] Crash making a linked object group local

was an error with make-local refactor & path updating.

UI: another tweak to panel header drawing, to get the checkboxes positioned right.

Fix: defining properties would fail with argument update=None instead of not
specifying the argument.

Fix #27981: opengl render + render slots not working.

This also revealed an issue where the opengl render float buffer was not linear,
and toggling back to a render slot would show wrong colors. Now it converts the
float buffer to linear so that this goes ok, disadvantage is that it's slower.

Fix #29393: operator preset compatibility issue due to renaming property to
avoid c++ keyword conflict. Added property back now duplicated, code generator
will avoid the conflict and this should keep things compatible.
