As far as I know, only DXTC is supported by any current consumer
hardware.  Intel might support FXT1 still, but I'm not sure.  Some
embedded (i.e., cell phone) hardware supports PACKMAN, and some embedded
PowerVR hardware supports their most recent texture compression format.

Not that I'm aware of.

Nope.  I don't think we were ever able to figure out exactly how it
worked on R128.  Patches welcome. :)
