[cairo] glitz WGL backend

[Maarten Breddels]

Good, someone is working on this. I tried to do it too, but text didn't 
render correcly,(only the 2nd glyph was ok, the rest was garbage), so i 
lost interest. Is it possible with your current code, to create a glitz 
context assuming there already is an opengl context. Using 
wglGetCurrentDC and/or wglGetCurrentContext it should be possible to get 
the HDC/HGLRC. This would be great for toolkits which provide opengl 
canvas'es etc. like Tk/wxWidgets/Qt.

I'm not sure if it's possible to do sth similar from XGL too, but this 
would be really interesting, otherwise i have no idea how it would be 
possible to display opengl cairo output on for instance an opengl canvas 
using wxPython.

PS: could you mail me your code, so i can try out some things?
