I used another patch which complicates the code somewhat, but old solution was too slow for my taste.
This should now speedup CTriangleSelector for animated meshes which call updateFromMesh regularly.
Also a fix: CTriangleSelector no longer resets it's boundingbox to 0,0,0 (that caused too large meshbuffers when a meshbuffer was not around 0), so basically also just a speedup.
