Sun Creator and XRender

Hello,

since the sunffb driver doesn't support the XRender extension but the
graphics processor supports alpha blending and a few other nice tricks
I've been poking around a bit to add this sort of functionality. The
problem seems to be that sunffb doesn't use xaa or the standard
framebuffer manager. so I couldn't get the included render code to work.
So my questions are:
- is there a text somewhere describing how to add xrender functionality
to a driver without using fbPictureInit() ?
- is there some more comprehensive ffb documentation available
somewhere? I think I know how alpha blending and so on is supposed to
work ( from reading the mesa driver source ) but there are still a few
more questions.

have fun
Michael
