Blender Git Loki

patch from Jochen Schmitt to get blender building with gcc4.7

Style cleanup of gpu rst file.

BMESH_TODO - Rewrite UV straighten tool for bmesh. (was commented out)

svn merge ^/trunk/blender -r43976:43995

Merging r43952 through r43994 from trunk into soc-2011-tomato

Fix for hardcoded to scons rules python abi flags and wrong behavior
of python bundling on systems where python is installed to /usr/lib64

Now ABI flags are automatically detecting (by checking all available flags
and checking if there's include directory exists for flag).
Also, automatically set PYTHON_LIBPATH to /usr/lib64 if python
scripts are stored in this folder.
Bundling python on *nix platforms is now checks if python is installed
to lib64 directory and if it is, python will be bundled to lib64
folder instead of lib.

This will make building on openSUSE a bit less annoying

Fix #30004: cycles brightness/contrast node issues. The formula used did not work
very well for colors that can be outside of the 0.0..1.0 range, giving +/- infinity
results.

Now we just use a simple linear contrast factor as proposed by Paolo Sourvinos, and
clamp values to be >= 0, and also make the parameters work more in the 0..1 range
instead of the 0..100 range, to be more consistent with other nodes.

Fix #30071: crash with cycles glsl, textures functions (which are stubs still)
got out of sync with node changes.

correct 2 sphinx warnings.

Use the same fancy compile output for .cc files as for .cpp files

small speedup for BM_SelectMode_Flush()
- don't check selected vertices for hidden faces.
- rather then counting total selected verts for a face, break out of the for() loop when an unselected vert is found.

fix [#30103] Select vertex groups works only in vertex select mode

add selection flushing matching whats in trunk.

add bake action into animation menu - this nifty operator wasn't available anywhere in the UI.

fix [#30101] Vertex colors disappear after leaving edit mode

this commit makes vertex paint check if it needs to rebuild the modifier stack when painting.
- when painting with no modifiers, do partial updates from polys to tessfaces while painting, skip re-tesselation.
- when painting onto a modified mesh, dont bother adjusting tessface colors - since the modifier stack will do this anyway.

both cases should be faster then before.

Fix for duplicated vertices in UV sphere when it's creating with large radius.

Issue was caused by not enough threshold limit used for removing doubles.
Switched to adoptive threshold value calculation based on smallest length
of segments in meridians and parallels.

Movie Clip Editor: manual calibration will now respect GP layer's hidden flag

use MPoly's rather then MFaces (since these don't necessarily exist) for drawing game engine bitmap font text.

minor edits to draw_tface_mapped__set_draw() to make it more efficient.

Code Cleanup:

macro for copying polygon settings

Fix #30102: Vertex and edge incorrect selections

Select Linked operator was setting Limit by Seams property automatically
depending on current selection mode. But this property only used to be
set to truth if selection mode is set to Face, in other cases this property
is being reused from previous operator run. This leads to incorrect
behavior of selecting linked in vertex mode after this operator was
used in face selection mode.

Code cleanup: remove duplicate OR'ing of CD_MASK_MDISPS.
