[Bf-committers] 2D coordinator to 3D coordinator

[dai longquan]

Thank you for you reply. I have work out this problem by  similar script
with you. But the numeric algorithm to get inverse of a matrix
invert_m4_m4()   is not consistent with  Matrix.inverted() which cause
significant numeric error for it should be. So from time to time the numeric
error will upsetting me.
