BGE Animations: Adding a new choice for vertex deformation for armatures, which can be found in the Armature's Skeleton panel by the Deform options. Before only Blender's armature_deform_verts() was used. Now users can choose a vertex deformation function that is optimized for the BGE. At the moment it is mostly a copy of armature_deform_verts() with various chunks of code removed, and the BLI_math code was replaced with Eigen2. In my test scene, the new function offered about a 40% improvement over armature_deform_verts() (17~19ms rasterizer to 11~12ms). The only current limitation that I'm aware of if that B-Bone segments are not supported in the BGE version, and I will probably leave it out. I would like to also limit the BGE version to 4 weights to make things easier for a GPU version, but this may just make things slower (sorting weights to find the top 4).
