Blender Git Loki

Added UV-mesh cache so editing is fast, implemented NurbTrim. DNA is still buggy.

small cleanup against mater to avoid conflict when merge-testing with multiview

Merge branch 'master' into blender-tiles

fix for crash at changing mass when not at frame 1

Fix for error when converting int -> unsigned int with strict compiler
flags.

Changed mesh sample definition to use 3 vertex weights instead of a
face index. This is easier to sample uniformly and avoids the need for
tesselation for evaluating.

Normalize the normal vector after sample eval to account for
interpolation.

Added a bool return to the eval function to give feedback on invalid
samples.

Added a basic RNA definition for the mesh sampling system.

Eval function to get a location and normal vector from mesh samples.

Usable random distribution algorithm.

Does not include area weighting yet.

Skeleton code for sampling meshes.

Merge branch 'master' into hair_system

Cycles: Further optimizations for Volume Light Sampling.

* Now we calculate ls->P only, which is needed for equi-angular sampling. If the scattering is successful, we call the regular light_sample() functions.

Only modify outline of selected pie items.

Proper fix for previous fix (tm)

Manipulator property toggle did not work. Add toggle operator instead

Proper fix of tooltips not exiting

Bending forces and damping for hair.

This adds some stiffness to hairs along bends, such that the hair does
no longer behave like a chain of freely rotating segments.

Note that there is no bending force on the root segment yet, which means
the hair swivels around the root point without resistance.

Fix tooltip sticking to button
