[Mesa-dev] [PATCH 1/2] mesa: Make sure _TexEnvProgram points at the current ff fragment program

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

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.
