Gtk offscreen rendering

[ecyrbe <ecyrbe gmail com>]

Hi everybody,

I'm wondering how far we are from the integration of the gtk+ offscreen rendering patch into the master branch?
I'm willing to help everyone working on this (and especialy on the win32 backend).
I have already suplied some patch in other sections of gtk+, mainly in win32 printing stuff and i'm familiar with the gtk+ internals.
I'm conviced that the future gtk 3.0 will need this for integration with a decent canvas implementation (like goocanvas or clutter). It's a shame that Qt has already these stuff implemented and not gtk+.
