| '''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. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/SGIX/swap_barrier.txt |
