I've gone back and forth on this. Ultimately I settled on the current setup
because it followed how Mesa and dri drivers already handle other similar
existing formats. The intent is to let the dri driver decide what the
hardware can and can't deal with, the first step being communicating to the
driver what format the GLUser has provided via a known mechanism. By the
same logic, it's the driver's decision as to what format the texture takes
when it gets to it's final resting place in video ram, thus the
gl_format_info.DataType field isn't really relevant here.
Some other minor nits inline, can't say if the approach in general makes

>From my recent assessment, adding more formats with full support would
offer more opportunities to picki target formats that require less CPU
processing of the GLUser texture. My intent is to use the GPU for this,
thus I'm not concerned for fully supporting the new cases by adding
Texstore functions and render target info.
