revert part of 48340, it causes uvs across islands to stitch in a different way (?) than before

svn merge ^/trunk/blender -r48370:48375

recent fix for #31581 could crash when doing edge slide on a mesh with no UV's.

code cleanup: compile with clang and quiet some warnings.

svn merge ^/trunk/blender -r48333:48370

Forgot these files in previous commit.

Fix for image node: The button draw function was using the image user pointer for displaying properties, which does not work correctly. The image node has to redefine image user RNA properties in order to make correct update calls and to have meaningful image layer names. For these properties the node pointer itself has to be used then.

Cycles: regular rendering now works tiled, and supports save buffers to
save memory during render and cache render results.


Implementation notes:

In the render engine API it's now possible to get the render result for
one render layer only, and retrieve the expected tile size in case save
buffers is used. This is needed because EXR expects tiles with particular
size and coordinates.

The EXR temporary files are now also separated per layer, since Cycles
can't give the full render result for all render layers, and EXR doesn't
support writing parts of tiles.

In Cycles internally the handling of render buffers and multi GPU
rendering in particular changed quite a bit, and could use a bit more
refactoring to make things more consistent and simple.

Move color management check stuff from blo_read_file_internal to setup_app_data

Fix for [#23375] "texture2D in custom 2D filters can get texture outside of game, resulting in ugliness" reported by Jacob F.

The 2D Filter system now only copies the game viewport instead of the whole window. This prevents 2D Filters from grabbing data outside of the game viewport. The textures for 2D filters are now also not forced to be powers of two (if NPOT textures are supported), which can save a little bit of VRAM.

fix for segfault on undo because of loading color profile info.

Fix #31835: OBJ Importer corrupts a model (crash in edit mode)

Added back face validation to BKE_mesh_validate_arrays.

This is needed because some addons (like OBJ importer) are reading
tessfaces and then converting them to ngons and validation of tessfaces
is needed before such a conversion.

Validation of faces would happen only if there's no polys in mesh.

code cleanup: cmake buildsystem edits, unused var warnings and better description for WITH_PYTHON_MODULE.
also disable workaround for some linux installs.

Basic snapping in node transform operator.

Snapping actually was working already, but grid spacing was set to 1.0, which is basically pixel size in the node editor. Increased this to 1x grid step for fine snapping and 5x grid step for rough snapping.

Grid drawing in node editor now draws 2 levels in slightly different shades to indicate the different snapping modes better.

Node editor also supports the general use_snap tool setting to enable automatic snapping during transform. For now only the incremental snapping is supported, in future could be extended to enable alignment between nodes in a number of ways.

document calling operators with undo enabled.

Fix #31929: VSE crash with relative paths and rebuilding proxies

code cleanup: when heat weighting dont loop through all polys when its not needed.

fix [#31940] crash with automatic weights

Removing channel manipulation from the Action Actuator Python API since this has been broken since the animation changes from Pepper. BL_ArmatureObject.channels should be used instead. For more information see bug #28843 for more info:
