Subject: i965: Render R8G8B8X8 as R8G8B8A8
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=58790043bb9e222f54994eba6ec78429d0d23625;p=mesa.git

i965: Render R8G8B8X8 as R8G8B8A8

The sampler can handle R8G8B8X8 (and substitute 1.0 for the fourth
component) but we can't use it as a render target.
