OpenGL extension SGIX.swap_barrier
This module customises the behaviour of the OpenGL.raw.GLX.SGIX.swap_barrier to provide a more Python-friendly API
Overview (from the spec)
This extension provides the capability to sychronize the buffer swaps of different swap groups.
A swap group is bound to a _swap_barrier_. The buffer swaps of each swap group using that barrier will wait until every swap group using that barrier is ready to swap (where readiness is defined below), after which time all buffer swaps of all groups using that barrier will take place concurrently.
This extension extends the set of conditions that must be met before a buffer swap can take place.
