Subject: i965g: make sure blend color packet header is initialized
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0e80e4ea7576733ede13f156a1dce644b1e6df89;p=mesa.git

i965g: make sure blend color packet header is initialized

We will emit this packet at startup (dirty == ~0), even if we haven't
had the state tracker call into brw_set_blend_color() yet.

This way is a little more efficient also.
