Important fix for damping loop.

This was causing great instability due to using the advanced velocity
after applying spring and external forces.

Now the velocity integration happens in the internal loop, but applies
precalculated spring/ext. forces as constant during the time step,
while incrementally calculating the next velocity.

Hair debugging: Draw vectors as a point with a direction (as opposed to
a line from a to b).

Clear hair debug data when rebuilding the solver data.

Revert "Squashed commit of custom split normals branch."

This reverts commit be5ac0929fc1496866aa69c55b18b2f5574b80e0.

Squashed commit of custom split normals branch.

Cycles: Fix wrong image update tagging, float vs. byte images

Fix T41068: 3D viewport shading - Material or Window vs. Rendered

Checked with Brecht, Cycles indeed expects generated to be in 0..1 space
instead of -1..1 as it is in BI.

Cleanup: BMesh arg name

Fix T41528: Error message on trying to import COLLADA triangle strips is wrong

Thanks to Maarten Gribnau for the patch.

ColorRamp: Use linear V for HSV/HSL blending

This matches RGB blending black/white for eg.

ColorRamp: HSV CW/CCW were flipped

Cycles: Drop support for CUDA 5.0 Toolkit, only 6.0 and 6.5 (recommended) are supported now.

Fix T41267: Wrong light distribution with when having objects with motion blur

Tests: remove support.run_unittest

Fix incorrect 2d stabilization for masks

Creation code complete - no way to test yet.

Merge branch 'master' into temp_custom_loop_normals

SetSplitModifier: code reorganization.

SetSplitNormals modifier: add a new 'from split normals' mode.

This adds the ability to set our split normals from target's split normals.
We first find closest vert, then select 'best' lnor by matching polys' normals.

Note that if target has stray vertices, modified lnors closest to those non-loop
target vertices will just get auto-normals. Not sure we want to add further
loops to find closest 'loop-compatible' vert?

Also, fixed a nasty dummy crash when swithing target to Edit mode!

Missing struct attribute in function declaration.
