OSX: omp script rework part2

OSX: omp script rework part1

OSX: Start with OMP_NUM_THREADS default unchanged, to let the user decide about optimized value, default == all cores used

correct spelling errors in comments

fix spelling mistakes in comments (and in some python error messages), nothing to effect translations.

svn merge ^/trunk/blender -r41005:41075

quiet some pedantic gcc warnigns

docs / clenup (no functional code changes)
- added API examples for mathutils.Color/Euler/Quaternion/Matrix.
- corrected own bad spelling matricies --> matrices.
- minor pep8 edits.
- update CMake ignore file list.

Another attempt to fix the failure of SVertex::getFEdge due to a discontinuity
of underlying FEdges introduced by chaining operations. The material of a
smooth FEdge is identified by the material index of the FEdge and the array
of materials in the SShape to which the first SVertex (i.e., vertexA) of the
FEdge belong. The present fix makes sure that the material index refers to the
intended array of materials, to avoid inconsistent reference and out-of-index
errors that lead to a crash.

Cycles: fix crash using uv + generated texture coordinates on a single mesh.

Cycles:
Add cmake path for the CUDA toolkit (default installation) on windows.

Cycles: material "sample as light" option, to make the integrator sample the
object as a mesh light or not. This may result in more/less noisy renders
depending on the situation, but should converge to the same result.

Cycles: enable multi closure sampling and transparent shadows only on CPU and
CUDA cards with shader model >= 2 for now (GTX 4xx, 5xx, ..). The CUDA compiler
can't handle the increased kernel size currently.

Cycles: revert unneeded branch change to particles UI script.

Cycles: add transparent shadow support, i.e. shadows through Transparent BSDF
shaders, enabled by default.

Cycles: enable improved closure sampling, this should give less noise for mix, add
and glass shaders. How well this will work on non-fermi GPU's is unclear still, it's
a bit heavy on register usage.

Cycles: fix F12 render not using render resolution for modifiers.

Cycles: fix sampling issue with certain (transparent) max bounce settings, and
tweak presets/defaults to use 128 instead of 1024.

Cycles: use mesh normals computed by Blender instead of computing our own,
solves an issue with poor mesh geometry.

Cycles: fix missing node editor redraw when assiging/removing materials.
