Subject: attrib: push/pop FRAGMENT_PROGRAM_ARB state
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6f1538f8b4b253ba7aa92c98997719ce3ca59451;p=mesa.git

attrib: push/pop FRAGMENT_PROGRAM_ARB state

This requirement was added by ARB_fragment_program

When the Steam overlay is enabled, this fixes:
* Menu corruption with the Puddle game
* The screen going black on Rochard when
  the Steam overlay is accessed

NOTE: This is a candidate for the 9.0 and 9.1 branches.
