[Mesa-dev] [PATCH] radv: reset the window scissor with no clear state.

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

IF we don't have clear state (which gfx10 doesn't currently)
we will fix to reset the scissor. AMDVLK will leave it set
to something else.

Marek also has this fix for radeonsi pending.
