 	I was actually talking about XV extension.  I know that XV does 
hardware video scaling (like 720x480 on an 800x600 resolution).  I was thinking 
mostly about possibly getting more poop out of vid cards that don't have XV 
(e.g. Matrox Millenium).  If it didn't have to software-scale and could instead 
switch hard resolutions, it might be faster.  I think XV does colorspace 
conversions as well though, right?  If so it probably wouldn't help too much.

 	Due to my incredibly odd setup requiring interlacing, XV, and very low 
frequency (NTSC) output, finding a video card that does them all is very tough. 
I've found a R128 that will do it all (although XV driver is buggy and has 
scaling problems).  My Matrox doesn't do XV, and my NVIDIA doesn't do 
interlacing.

 	Sounds like a good plan.  RANDR is a pretty new feature for X IIRC.

 	Probably just not enough vitality to have it a priority yet.
