Summary	0001368: Subclassing Matrix silently fails
Description	To work around issue 1364 in the build I have, I tried to subclass Base.Matrix to override the move method. That was accepted, and I can construct objects of the subclass. But it doesn't actually work; the constructed objects have the wrong class (the base class Base.Matrix). It would be good for subclassing to work, but if it's not going to work, the FreeCAD builtin classes should be marked as not permitting subclassing.
Steps To Reproduce	class M(Base.Matrix): pass m=M() assert (type(m) == M)
Tags	No tags attached.
