Multi-threading support for transform modes: bevel-weight, crease, push-pull, rotate, shear, shrink-fatten, skin-resize, to-sphere, trackball & translate. This is done using a parallel loop over transform data. From testing a 1.5million polygon mesh on a 32 core system the overall performance gains were between ~20-28% To ensure the code is thread-safe arguments to shared data are const.
