Cool.
But the folks in the GTK2HS mailing list told me Glitz never really took of :-(
I hope they are wrong :)

I should have mentioned that my tests have been done only on Windows and OSX. I guess I would have to try on a system that supports XRender to compare.
Unfortunately, the target audience of our application are mostly windows and OSX users, so although it would be great that Cairo performs fast on unix variants, it would be of little value to us, unless of course XRender also runs on Windows/OSX somehow :)
from the glitz page I refered to:
The semantics of glitz are designed to precisely match the specification of the X Render extension. Glitz does not only implement X Render features like component alpha and image transformations, but also support for additional features like convolution filters and color gradients, which are not currently part of the X Render specification. The performance and capabilities of glitz are much dependent on graphics hardware. Glitz does not in any way handle software fall-backs when graphics hardware is insufficient. However, glitz will report if any requested operation cannot be carried out by graphics hardware, hence making a higher level software layer responsible for appropriate actions. Glitz can be used as a stand-alone layer above OpenGL but is also designed to act as a backend for cairo, providing it with OpenGL accelerated output. That's why it would be good to know whether glitz is still supported (and compatible with current cairo): it, or something like it, would provide direct access to hardware-accelerated cairo functionality on all OpenGL platforms (without the current Haskell-land dependency of cairo on Gtk2hs; though software fallbacks for missing hardware support would seem essential).
