[Bf-committers] Scale from Matrix

[Campbell Barton]

Hey All,
have a problem, sound simple but cant find a soltion.

I need to get the scale value of a matrix.
arithb.c's  Mat4ToSize  works but the returned scale is never negative, 
so at the moment, I cant tell if a the model is flipped by it matrix.

Obviously its in blender somewhere, bacause the SizeX: value can be 
negative.

Anyone know how to do this?
