Subject: vc4: Use the blit interface for updating shadow textures.
X-Git-Tag: upstream/17.1.0~19496
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=adae027260bedc7af73e5cc7a74af3cafa4ab460;p=platform%2Fupstream%2Fmesa.git

vc4: Use the blit interface for updating shadow textures.

This lets us plug in a better blit implementation and have it impact the
shadow update, too.
