2016 GSOC project by @nathanvollmer, see D2150 - Mirrored painting and radial symmetry, like in sculpt mode. - Volume based splash prevention, which avoids painting vertices far away from the 3D brush location. - Normal based splash prevention, which avoids painting vertices with normals opposite the normal at the 3D brush location. - Blur mode now uses a nearest neighbor average. - Average mode, which averages the color/weight of the vertices within the brush - Smudge mode, which pulls the colors/weights along the direction of the brush - RGB^2 color blending, which gives a more accurate blend between two colors - multithreading support. (PBVH leaves are painted in parallel.) - Foreground/background color picker in vertex paint
