Merged changes in the trunk up to revision 36408.

Style Cleanup
- duplicate cases in if/else
- calc inside sizeof(...)
- redundant NULL checks.
- assignment to self.
- fix error getting text prefix for screen ID button.

Cycles: build without GLUT test app by default.

tweak image stamp, was 1px overlap and text was drawn too far up.

- remove UV_OT_select_inverse, instead use invert option for UV_OT_select_all.
- fixed INVERT option for UV_OT_select_all.

Cycles: fix build issue with Blender includes.

- Description of texture angle sources and stroke methods
- Fixed bug with empty tooltip for some ENUMs

Fix #27239: "A" menu in Sculptmode fails

Simple incorrect property accessing fix (enum_items vs. items).

Additional change: removed hotkey to toggle airbrush in sculpt mode
TODO: incorrect hotkeys are shown in stroke method menu, but it's how
hotkey string detecting works now.

replace inline string searches with BLI_findstring(), strcmp(..., ""), with char comparisons.

copying texture point density was using inline dupalloc rather then BKE_copy_pointdensity() which NULL's runtime pointers.

fix for r36399
- missing copy, free calls to curve falloff.
- missing localizing call for texture preview.
- also moved versioning into do_versions()

=bmesh=

Holding shift in knife mode will turn
off edge/vert snapping for original
geometry. The snapping threshold for
knife cuts is also halved, for additional
precision.

=trunk=
Made some improvements to the point density texture. Added support
for tweaking the falloff with a custom curve. Also coded new
falloff types based on the age or velocity of particles.

Also added a test break check to the volumetric shade cache code,
to avoid nasty hangups from the preview render (on render, exit,
etc).

=bmesh= fixed edge loop preview, patch from Francisco De La Cruz. man did I hate writing this code, thanks Francisco for fixing this bug :)

Fix #27224: Extrude Repeat Mesh doesn't have options

Poll function was too strict for this case that's why there was
no options in operator panel.

Additional changes:
- Added 'direction' parameter to operator so now extruding
could be made from script by providing direction vector.
- Fill this direction vection in operator's invoke functions
so abjusting offset/steps in operator panel gives better visual
feedback -- direction stays unchanged so user could easily see
final result.
- Made some tweaks to soft limits, so adjusting values by mouse
drag isn't such confusing now.

Tested in normal mode (from 3d view), as script and in background mode.
Haven't noticed any regressions.

whitespace edits for bpy api, split some really long lines.

Fix one more crash introduced with r36384: trying to bake resulted in a segfault

Also, use tabs for indentation in previous fix for the same crash

fix crash using freed memory with SCREEN_OT_screen_set while the current screen has a full area.

fix for render stamp text drawing too low.

fixed a crash introduced in r36384
where the preview render was calling getCam before setting the scene.
