[Mesa-dev] [PATCH] nv50: mark scissors/viewports dirty on context switch

[Ilia Mirkin]

Commit 246ca4b001 ("nv50: implement multiple viewports/scissors, enable
ARB_viewport_array") added dirty tracking to scissors/viewports. However
it neglected to mark them all as dirty on a context switch. This fixes
an apparent regression in webgl in chrome, but probably in any
application that switches contexts.

I'm probably going to push this out very shortly, as it is unlikely to be
reviewed quickly and this is an annoying regression, but sending out to list
so that I can make any necessary follow-up fixes, should review comments
arrive.
