The advantage is that lookup is done before filtering, while with  
shaders you need to do the filtering yourself.

IIRC from XDS weren't there some ES extension that actually fit what  
hardware does better, or doesn't it fit the needs of apps as well?  
Then again I'm not for keeping this code.

Cheers Jakob.
