Selection: avoid uninitialized memory read with occlusion queries

Fix for hair child roughness.

The fixed-function roughness was not getting used once the curve
roughness has been enabled at least once.

Adjust GLSL drawing of window coordinates from camera view (use camera
bounds instead of window bounds). Fixes remaining part of T43346

Fix for unfreed effector weights in hair dynamics.

The internal cloth modifier effector weights get replaced temporarily
to make the cloth sim use the particle weight settings instead. But
the particle sim was not putting back the original weights, which can be
non-NULL in case the cloth sim allocated these already. Messy design ...

Fix for unfreed memory due to unnecessary early exit in the free
function.

Fix for unfreed memory of internal hair cloth modifier pointcache.

Cycles: Remove redundant calculation of w in recent cubic commit

Was rather harmless since compiler will optimize it out, but nice to get
rid of this anyway.

Fix T43511: Major slow down with many instanced objects in cycles GPU

Slowdown was caused by watertight intersection commit and follow-up workaorund
for compiler crash which uninlined utility function which rotates the ray.

Now it's only uninlined for sm_50 and sm_52 experimental kernels which are the
only ones which failed to compile.

Rendering still might be a bit slower but at least shouldn't be that dramatic.

cleanup: style/spelling

Avoid warping the pointer when doing constrained texture painting
strokes

Cycles: Fix inconsistent command line used for runtime kernel compilation

Basically build-time compiled kernels were using --fast-math (which is correct)
but run-time compiled did not.

minor edits to last commit

Fix T43501: Crash on custom node tree creation

Fix for Freestyle view map caching not properly updated upon changes of render resolution and scale.

Problem reports independently by Light BWK and Folkert de Vries, thanks.

BMesh: tool to ensure all faces are convex

Access from Mesh -> Cleanup

BMesh: BM_face_triangulate take edge array

To access edges created between the tris.

Cycles: Indentation fix for the previous commit

Cycles: Implement cubit image interpolation on CPU

Basically title says it all. Could be not totally optimized but the code is there now.

Add extra Cycles regression tests

This new tests are aimed to issues/regressions reported to the tracker.

Cycles: Allow paths customization via environment variables

This is for development and test environment setup only, not for
regular users usage hence no mentioning in the man page needed.
