Subject: st/nine: Back scissor to nine_context
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9498613607aa9bf42a36db0462f5e38b1d1f4c60;p=mesa.git

st/nine: Back scissor to nine_context

Part of the refactor to move all gallium calls to
nine_state.c, and have all internal states required
for those calls in nine_context.
