Subject: i965/curbe: Look at SYSTEM_VALUE_FRAG_COORD instead of VARYING_SLOT_POS
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9265e9d11aa20697d3d9871c2bd0b5402b135dbd;p=mesa.git

i965/curbe: Look at SYSTEM_VALUE_FRAG_COORD instead of VARYING_SLOT_POS

When transitioning gl_FragCoord over to a system value, we missed one
instance of VARYING_SLOT_POS in i965.  As of this commit, i965 has no
references to VARYING_SLOT_POS.
