Re: [Mesa3d-dev] How do we init half float tables?

Both ways are useful: single pixel decompression for texture sampling, whole block for whole image conversions.

FWIW, I don't see any new s3tc formats. rgtc will not be handled by s3tc
library since it isn't patent encumbered. util_format_is_s3tc will not
include rgtc formats.
(Though I guess that external decoding per-pixel is really rather lame,
should do it per-block...)
