I'm trying to programmatically determine whether a given CIFilter is  
usable on the current graphics hardware, but I can't find any  
definitive answer on how to do this. In Quartz Composer I can check  
for given OpenGL extensions and hardware acceleration, which I  
imagine is how I'm supposed to do this, except I'm not using Quartz  
Composer and I don't know what combination of extensions/acceleration  
is necessary for my filter. Is there any good way to figure this out,  
or am I going to have to try and find computers with different  
graphics cards to test with? And even if I do the testing, how am I  
supposed to detect the extensions/acceleration availability?

Thank you,
Kevin Ballard
