* Added "Initial Color" setting for surfaces. You can for example set color from UV mapped texture or from vertex colors. * Added clamping option for "wave" brushes. * Merged smudge and drip adjacency search code. This fixes some issues with drip effect and makes code easier to maintain. * Some adjustments to the bounding box generation code. * OpenMP is now completely disabled if no compile flag is set. * Wetness values are now properly clamped on vertex surfaces. No more black dots on >1.0 wetness. * Textured brushes now use same function calls as internal renderer, instead of modified duplicates. * Moved operator code to editors/physics/. * Re-enabled some particle brush optimizations. * Fixed sometimes incorrect volume brush influence. * Fixed possible crash when using a brush that uses "Voxel Data" texture simultaneously with material preview or render. * Fixed texture mapping issues for "Object Center" brush. * Fixed possible crash/corruption when duplicating brush object that uses color ramps. * Other tweaking and code cleanup.
