Make toplevel transparent windows work on Mac OS X
This patch includes a few different fixes to make transparent toplevels
work on cocoa.
- When setting alpha on the toplevel, it also needs setOpaque:NO
- The OpenGL context needs a separate flag for this to work.
- Make sure setOpaque fighting between setMask, setFormat and
setOpacity ends up correctly
