I have used pix_write to grab a 3840x1200 (two Cinema displays
fullscreen) before. It really depends on what the graphics
hardware will allow you to do. We impose precisely zero
restrictions on the size (apart from the 23 bit Pd limit).

...like chris says, we don't limit you, but your hardware does ;-)
The salient parameter here is MAX_TEXTURE_SIZE &/or
MAX_RECTANGLE_TEXTURE_SIZE_EXT: in general, nvidia hardware tops out
at 4096 and ATI at 2048...but a software renderer usually does
16384...btw, I'm getting this info from http://homepage.mac.com/ arekkusu/bugs/GLInfo.html

...so, if you want something higher than your hw can handle, you can
always do a multiple pass render changing the view frustum and then
stitch the two screen grabs in another program...
