Fix T41661: Added to main repo graph, science_lab and softimage themes.
Fix OpenGL error on cycles rendered viewport.

We queried the wrong value when looking for the bound 2D texture. This
is not totally robust because currently bound texture may not be a 2D
one, but this should work for now.
OSX: fsmenu cleanup
glutil: use ints for drawing functions

shorts would wrap sometimes & many inputs were ints already.
Fix T42145: EditMesh Bevel tools had no clamping option.

Missing feature already present in Bevel modifier, useful and rather simple to add.
Operator to define render border from rendered image editor

This way it is possible to define render border directly from the image editor,
which is useful for at least three things:

- If viewport is really optimized out (simplified etc) then it might be hard to
  guess which exact area you're mainly interested now.

- No need to switch to the viewport to do render border tweaks, could be useful
  when doing compositing.

- If one need to look at particular pixel(s) which is real handy for debugging
  render engines (both Cycles and BI).

D801: Freestyle: remove old and unused stroke shaders

This patch removes several stroke shaders written in C++ that are unused
and don't serve a real purpose any more.  The removed shaders are:

  - BPy_ColorVariationPatternShader
  - BPy_StrokeTextureShader
  - BPy_TextureAssignerShader
  - BPy_ThicknessVariationPatternShader
  - BPy_fstreamShader
  - BPy_streamShader

and a few more that weren't even exposed to the Python API.

Some minor edits were made by the reviewer.

Implement custom names for render slots

Basically the title tells it all, quite straightforward implementation.

The only thing is the image.render_slot which used to represent the active
render slot index is now moved to image.render_slots.active_index.

Cycles: Remove redundant float4->float3 conversion

Not as if it gives noticeable changes render-time, but it's just weird to
convert float4 to float 3 to just access individual x/y/z components.

Plus some compilers might be more stupid than GCC and don't optimize this
out well.
InstallDeps: Fix wrong OPENCOLLADA settings in final messages in some cases.

Fix T42139, vertical noise stripe patterns in noise texture.

Two fixes here (only the second one is strictly needed to fix the issue,
but both make the system better).

First is introduction of a random generator array for use with threaded
systems where each thread needs to access its own number generator.
The random texture now uses this so it should not be influenced by other
random generator reseedings of the main random generator like it did
before.

Second, I reshuffled the texture code to resample the upper bits of the
random number first. According to Numerical Recipes, this is where the
most variance can be found, so by sampling those we avoid correlation
issues. Also, multiplying here is not ideal because if a pair of bits
are zero, then the whole result will also be zero.

Overall this is much more random (tm) than before, however result will
also be brighter, since we now have less black spots. Tweaking the
brightness/contrast should somewhat fix that, generally having the same
result as before is not possible anyway if we are to really fix this.

Also, seems like exposing procedural depth might be nice here since it
influences the precision of the texture lookup.
