These patches implement wxRegion and the ShapedWindow sample. I stole the ruby image from ruby-lang.org. Shamelessly. Maybe someone has a better image we can use for the shaped window. It didn''t seem to make sense to use the Python image. I''d like something even bigger than what I stol^h^h^h^hmade, preferably. Image goes in icons. I had to %ignore one function in wxRegion.
