Ok, heres what I've got so far:
http://users.ox.ac.uk/~newc2303/gpupatch.txt
Details:
- All effects implemented except for 6tap+scanline, lq and hq
- Behaves exactly like the x11 software driver when in windowed mode
- With no resize effect selected, behaves exactly like the old gl driver
- Area
Ok, I overestimated the size of the lookup texture. I've now
implemented the hq2x algorithm and it runs at a pretty favourable
frame rate.
Are the developers interested in merging this? If so, which version of
xmame would you like me to diff against?

I'm not sure what's easiest for Lawrence, but if you do a diff against
the CVS over at mess.org, either Lawarence or myself can check the
code in and get some more user testing with it.

I used the ARB extensions so it should work on all cards supporting
fragment programs.

This is a bad patch, it is full of indenting changes. It is much
better to sumbit whitespace changes as a separate patch.

I'm not sure P-buffers are the onl

This page shows some vector effects done in the GPU

Would it be difficult to add effects like this as well?

As said, this is incompatible with the artwork system, we already have
opengl vector code, maybe this can be exte
Absolutely. You just need your curved surface approximation
and texture coordinates to match.
While you're at it you could use multitexturing and put a glare
on it, too. OK, maybe not. ;-)

I just committed hq2x support for the rewritten software effect code to
CVS, so it should be almost no effort todo a diff against CVS now.
I look forward to receiving a diff against CVS from you. I'll try to get
it to work on my ATI9250 and commit it to CVS. Assuming that the code
isn't totally
