* Division by zero fix for TNT SVD code. * Sound fix, in case ffmpeg decode fails, don't use the samples. * Fix for incorrect bounds of transformed objects in new raytracing code. * Gave memory arena's a name used for allocations for easier memory usage debugging. * Dupligroup no_draw option was using layers but not restrict view/render setting. (not a bugfix exactly but would do display list context switching while drawing for no reason). * Fix objects instanced on hair particles not giving consistent results when the object is transformed. * New math functions: madd_v4_v4fl, len_squared_v3v3, interp_v4_v4v4v4, mul_v4_m4v4, SH and form factor functions, box_minmax_bounds_m4. * mul_m4_m4m4 and mul_m3_m3m3 now accept the same pointers for multiple arguments. * endjob callback for WM jobs system. * Geometry node uv/color layer now has search list/autocomplete. * Various small buildsystem tweaks, not strictly needed yet in trunk.
