[Mesa-dev] [PATCH 16/20] mesa/formats: add new mesa formats and their pack/unpack functions.
Iago Toral Quiroga
itoral at igalia.com
Tue Nov 18 00:44:04 PST 2014
From: Samuel Iglesias Gonsalvez <siglesias at igalia.com>
This will be used to refactor code in pack.c and support conversion
to/from these types in a master convert function that will be added
later.
