Another problem that popped up after some more thoughts on this is, that cairo
doesn't seem to be thread-safe. So we need a way to give surfaces to the app
and tell the app to draw them in it's main loop.

For this we could use signals and I don't see another solution yet as the
drawing should happen ASAP.

Also we probably have to do some more magic with the surfaces, maybe ask the
app to set a surface and then we create "similar" ones to that surface and give
them to the app and the app can blit it on it's surface and has to free it
afterwards.
