Vector displacement maps (VDM) provide a way to create complex displacements that can have overhangs in one brush dab.
This is unlike standard displacement with height maps that only displace in normal direction.
Forms like ears, curled horns, etc can be created in one click if VMDs are used.
This patch reads the RGB channels of a texture in a brush stroke and interprets them as individual vectors, that are used for the vertex offset.
As of now, this is only working for the draw brush using the area plane method. Symmetry and radial symmetry is working.
Sculpt: Store inverse of brush_local_mat beforehand so it won't be calculated for every displaced vertex
Brush_local_mat_inv is needed to transform vectors of a vertex displacement map back to object space.
Sculpt: Added hint in tooltip that vector displacement works only with area plane mapping
