  • Revision ID: tarmac-20131030203120-bxn8whir9ao7rip7
Add support for the GLX_EXT_buffer_age extension on hardware that supports it, which should result in a nice speed-boost due to the fact that we no longer have to abuse fillrate by retaining old frame contents, and instead asking the driver how defined the current frame is. Fixes: https://bugs.launchpad.net/bugs/1024304.

Approved by PS Jenkins bot, Christopher Townsend, Marco Trevisan (Treviño).
