that doesnt sound very a
Hi list,
I've been thinking about ways to implement a combined "wait for vblank
and buffer swap" operation. But somehow I can't get the pieces together
partly because I have a pretty vague understanding what the hardware
does or can do on a low level.
First a short summary of the problem. Current

The thought of making a generic texture format selection routine had
occured to me, too. But it seemed to be too much hardware dependent and
I didn't feel like spending much thought on a general solution. Your
suggestion is quite general but I'm not sure it would be worth the
effort.

Thanks for the patch. This is perfect timing. I worked on a first gtk2
release last weekend and uploaded it a few minutes ago ;-). I had a
brief look at your patch. It looks like the first round of changes I
made myself. My current version goes a lot further using new gtk2
features like stock icons
