OpenGL extension SGIX.swap_group
This module customises the behaviour of the OpenGL.raw.GLX.SGIX.swap_group to provide a more Python-friendly API
Overview (from the spec)
This extension provides the capability to synchronize the buffer swaps of a group of GLX drawables. A swap group is created, and drawables are added as members to the swap group. Buffer swaps to members of the swap group will then take place concurrently.
This extension extends the set of conditions that must be met before a buffer swap can take place.
