BGE Animations: BGEDeformVerts() now handles normals instead of relying on BL_MeshDeformer::RecalcNormals(), which BlenderDeformVerts() still uses. As expected, the BGEDeformVerts() version isn't as accurate, but it avoids a sqrt per vertex. This gives about a 15~20% improvement in time spent on the rasterizer in my test scene, which resulted in about 5 more fps. However, the main reason for the new normal code is it will be easier to do on the GPU (doesn't rely on neighbor information).
