Subject: r600g: add BC4/5 to RGTC conversion
X-Git-Tag: mesa-7.11-rc1~2017
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2a6cce09e356a33337dbc193d8a580d0faab8915;p=platform%2Fupstream%2Fmesa.git

r600g: add BC4/5 to RGTC conversion

this doesn't do anything much since the rest of mesa doesn't
support RGTC yet.
