==========
Bugfix #4951: This might be a serious change for python script writers.
-- ob.getMatrix('localspace') did not return the correct matrix when the object
had a parent; this has been corrected.
-- ob.setMatrix(m) did not work predictably (more correctly, in an easy-to-
predict manner) when an object had a parent. The method has been changed
so that if thee is a parent, it ASSUMES the matrix is "localspace",
relative to the parent. The documentation now states this.
-- ob.mat and ob.matrix are now read-only attributes, while ob.matrixLocal
(which calls Object_setMatrix() ) is now read-write.
Ton is not thrilled (is that a fair summary, Ton? ;-) with this method since
the ob->obmat is calculated from the loc/rot/size attributes of an object.
I'll let him speak on this, but I believe his desire is for this method to be
deprecated in the future and replaced with something else.
