Subject: mesa: Make sure _TexEnvProgram points at the current ff fragment program
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=34db7a8c1e775aaefad7952133e087f1c1a569f6;p=mesa.git

mesa: Make sure _TexEnvProgram points at the current ff fragment program

At least one place, the _mesa_need_secondary_color function in
state.h, uses this to make decisions.  The next patch in this series
will add another dependency.  Ideally, this field would go away and be
replace by a flag or something.

NOTE: This is a candidate for the 8.0 branch.
