wxWidgets/wxPython/demo/GridHugeTable.py
Robin Dunn 9416aa89ca Implemented the first phase of OOR (Original Object Return). See the
text in the demo for more details of what this means, but in a
nutshell methods such as wxWindow.GetParent or FindWindowById will now
return a shadow object of the proper type if it can.  By "proper type"
I mean that if the wxWindow pointer returned from FindWindowById
really points to a wxButton then the Python object constructed will be
of a wxButtonPtr class instead of wxWindowPtr as before.  This should
reduce or eliminiate the need for wxPyTypeCast.  (Woo Hoo!)  The
objects returned are still not the original Python object, but that is
the next step.  (Although it will probably only work on Python 2.1 and
beyond because it will use weak references.)

A few other minor tweaks and fixes and additions for things found
while doing the OOR stuff.
