When using MatrixToAnglesAndScale the order of angles is wrong.

vector mat[3];
Math3D.AnglesToMatrix( "1 2 3", mat );
SCR_Math3D.ScaleMatrix(mat, 5);
vector ang;
float scale = Math3D.MatrixToAnglesAndScale(mat, ang);
Print(ang);
Print(scale);

SCRIPT : vector ang = <2,1,3>
SCRIPT : float scale = 5

The expected output would have been <1,2,3>.

Even worse when using MatrixToAngles it just does whatever happens here in the correct order but the wrong value

vector mat[3];
Math3D.AnglesToMatrix( "1 2 3", mat );
SCR_Math3D.ScaleMatrix(mat, 5);
vector ang = Math3D.MatrixToAngles(mat);
Print(ang);

SCRIPT : vector ang = <1,10.0494,3>

The expected output would have been <1,2,3>.
