Re: Performance of many widgets

[Brian Phelps <lm317t gmail com>]

Performance really decreases in my experience with large resolutions and
 older hardware.  Try it with an older 1GHz shared graphics card machine
 at 1024x768 with just 40 buttons spread out and it takes 3/4 a second 
to a second.  No need to try it with thousands.  Try it with 40 on a 
large screen.

Any UI response more than a tenth of a second is unacceptable.

What is the most practical way to speed this up?  I know I can blit to the screen much faster than this according to x11perf

Man, I ran that code with four *thousand* buttons, and it still only
took one *second* to toggle them all.  How fast do you want it to go?!
