not a bug, a documented feature..

So I was pointed to the Pyrex docs covering "special methods". Apparently the behavior causing the segfault is intentional, and yes, the __new__ of the base type is automatically called (so it's extending rather than replacing).

Now I need to start defining superclass __new__ as:
def __new__(self, parent, *extra, **extranamed) :

In other news, Zach has had me focusing on soy.Window rather than continuing with the camera/bodies/etc. It's working nicer now, with a background and keeping the aspect it was created with. There's a ton more surface things that can be done with it but I think this is enough for now.
