Cycles: optimization to not compile shaders and load images that are not
used by any mesh/lamp/world.

minor changes to select similar,
- replace ngon_fake_area() with generic call to BM_face_calc_area().
- add defvert_find_shared() utility function.

Fix for own r51737.

Refactoring of draw code showed another problem: The MCol we want to draw may change without dm rebuild (e.g. when enabling solid textured option)! Also, choosing which MCol layer to use in GPU code is stupid, different draw modes use different layers/order of precedence!

Solved this by adding a new colType parameter to GPU_color_setup, and removing any 'color choosing' code from gpu_buffers.c.

Fix build for recent bmo commit (gcc wants a return value in any case! ;) ).

bad naming, the bmesh operator only tags, not selects.

code cleanup: move select-similar bmesh operators into their own file since there are 3 operators here that share
utility functions with eachother but have nothing in common with other operators in bmo_utils.c

add the option to select Equal/Greater/Less when selecting similar.

Recently addons were submitted for review and this was the only advantage they had over blenders existing internal
select-similar tool.

add option to select face by matching number of sides.

correct assertion

Disallow collection add/remove/clear/move when drawing. - similar to how writing to attributes is disabled.

Removing BLENDER_GAME from the COMPAT_ENGINES set for the sun lamp's Sky & Atmosphere panel since it isn't supported in the BGE.

Additional UI tweaking: the Freestyle toggle of the Include section in the Layers
panel is greyed out when Freestyle is globally disabled.

Further tweaking of the recent UI changes (new layer context), mostly by splitting
the big layers panel in three, and fixing Freestyle's panels poll function to hide
them when Freestyle is disabled.

Patch contribution by Bastien Montagne, thanks!

Fix: wrong brush drawn in image painting, image editor if uv sculpt is on. Now the correct paint struct is returned and the image zoom is calculated correctly

Bugfix:

3D text object editing, ALT+Backspace trick is back to construct special characters.
Like: O , Alt+Backspace , / creates an O with a / in it.

It also makes plus-minus, unequal, copyright, 1/2, 3/4. etc. Easy method you
never forget after using once!

Got broken with adding UTF support a year ago.

fix [#33011] "System" tab empty in OSX - file browser
* items were wrongly added too SYSTEM_BOOKMARKS rather than SYSTEM, now fixed

Buildbot: hopefully fix for missed sound on glibc2.11 slaves

YACBSF. Yet Another Classic Blenderplayer Stub Fix.

To keep my commit rate high! :)

Yet another hanging variable in event code - code cleanup woes.

This should make trackpads work.
