[Bf-python] rotation matrices

[Tom Musgrove]

Hi,

could we also have the optimized rotation matrices available?

This function is a 1000% faster than using the current method.

Ie instead of


rxmat=Blender.Mathutils.RotationMatrix(AngleX,4,'x')
rymat=Blender.Mathutils.RotationMatrix(AngleY,4,'y')
rzmat=Blender.Mathutils.RotationMatrix(AngleZ,4,'z')
rotatedmat = rxmat*rymat*rzmat

we should be able to do

rotatedmat = Blender.Mathutils.XYZRotationMatrix(AngleX,AngleY,AngleZ,4)

This is needed for things like doing BVH import and export efficiently.

Thanks,

Tom M.
