Description Neil Roberts 2011-10-18 10:50:01 UTC

Looks like there is a cut and paste error which means the meta save/restore code won't save the active program if it doesn't have a fragment shader. Please see the patch.

meta: Fix saving the active program

When saving the active program in _mesa_meta_begin, it was actually
saving the fragment program instead. This means that if the
application binds a program that only has a vertex shader then when
the meta saved state is restored it will forget the bound program.
