Wait no that's broken too. Try the new version here instead...
In fact, texture tiling shouldn't be a problem since the byte offset
will always be a multiple of 1024.


Hi Roland;

It works!!

I had texture size set to 512 in r200 driver. Do you mean that with this patch, it'd work even if I had not set it to 512? if so, what would be the new limit?

Thanks for all your help.

I will send another email regarding viable volume rendering using open source mesa/dri/r200.
