The gtkglext stuff seems to be working prertty nicely - it even works on my
r500 ATI card where I don't even have 3d X driver support, or even 2d accel!

Sometimes though it does not refresh the screen properly. Asan exmaple, if 
i'm using a xterm and say type 'pwd<enter>', i'll see the 'pwd' characters 
typed, but not the newline and not the command output - until I type another
character or move the mouse. So it seems the screen refreshs may be getting 
delayed somehow.

Given that it works at an acceptable speed even without an accelerated X
driver I figure we ought to automatically enable it if the configure script
finds the neccessary library.

Dan.
