Subject: fix bug with generated fragment programs if vertex shader is active
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bf4a0fafc86bba8dc868cf30244a237e33645164;p=mesa.git

fix bug with generated fragment programs if vertex shader is active

When generating a fragment program from fixed function, checking
texUnit->_ReallyEnabled is not sufficient, need texUnit->Enabled too
since the former also represents texture enables from an active vertex
shader.
