Subject: i965: Make Gen6+ renderbuffer surface updates not depend on NEW_COLOR.
X-Git-Tag: 062012170305~3202
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9ae10e9cbdfce6404a3d86188f2897d8f5d0dcb2;p=profile%2Fivi%2Fmesa.git

i965: Make Gen6+ renderbuffer surface updates not depend on NEW_COLOR.

NEW_COLOR is only needed on Gen4-5 as brw_update_renderbuffer_surfaces
only uses ctx->Color when intel->gen < 6.

This should reduce unnecessary state updates.
