Subject: swrast: remove out of date comments in s_texfetch_tmp.h
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a19d60faefa91678dd6a5e38ae7350625523f71e;p=mesa.git

swrast: remove out of date comments in s_texfetch_tmp.h

The comments were out of date and redundant (the functions are
pretty much self-explanatory).
