Tidying options, line based strokes do not support stroke smoothing

Make fill tool listen to brush strength (Allows to quickly do semi-

Code cleanup: remove a duplicate define

added gpuGetViewport and added GPU_SAFETY checks to GPU_state_latch (state should be set before gotten)

Changed method of detecting infinite loop in gpu_check from a count to seeing the same error flag twice

added gpuErrorSymbol to go with gpuErrorString

putting GPU_mipmap_2D declaration in the proper header file (required letting creator.c include GL/glew.h)

Used the 'source_group' feature in CMake to organize the GPU source files better in Visual Studio

Volume:
* Comment some unused variables to silence a few compile warnings.

Merged revision(s) 60246-60320 from trunk/blender into soc-2013-dingto.

Branch maintenance:
* Bring the brach in sync with hair bsdf and ao_alpha code from trunk, somehow didn't work in r60244.

rigidbody: Don't handle collision after hitting a trigger

rigidbody: Code cleanup

Make functions private that are only used internally.
Also remove a nested if statement.

rigidbody: Code cleanup

Avoid mixing bool and int.

rigidbody: Flag bodies for validation when changing shape

This fixes a pretty old crash that occurs when changing the collision
shape to a mesh shape during simulation.

Thanks to Thomas Beck (plasmasolutions) for the report.

rigidbody: Fix crash switching to a mesh shape during simulation while using deformation

Thanks to Thomas Beck (plasmasolutions) for the report.

rigidbody: Update 3D view when changing the shape via operator

rigidbody: Only allow static-static collision when trigger is kinematic

This way passive object don't activate passive objects when using
activation on collision.

rigidbody: Don't try to deform shapes if we don't have a derived mesh

rigidbody: Abort mesh shape creation when we can't get a derived mesh

Would only assert before, now just return.

Thanks to Thomas Beck (plasmasolutions) for report.
