[Mesa-dev] [PATCH 3/4] i965/blorp: Add more destination flushing

[Jason Ekstrand]

Right now we just always flush the destination for render and aren't
particularly careful about depth or stencil.  Soon, flush_for_render
isn't going to do the same thing as flush_for_depth and we may be doing
a good deal less depth flushing so we should be a bit more precise.
