Robin Dunn 54b9688254 Enabling the use of masks for wxGTK in some of the demos
wxWindow.GetHandle returns the X-Window instead of the GtkWidget
pointer so the X-Window can be given to other Python modules such as
VTK.

wxPython.lib.vtk updated to get the window handle at widget creation
instead of in the constructor.
