OpenGL extension SGIX.tag_sample_buffer
This module customises the behaviour of the OpenGL.raw.GL.SGIX.tag_sample_buffer to provide a more Python-friendly API
Overview (from the spec)
The extensions defines a special purpose fast multisample clear. This clear can be used with some restrictions as a significantly faster alternative to Clear(DEPTH_BUFFER_BIT).
The extension is based on the RealityEngine architecture and will probably never be supported by any other architecture.
The official definition of this extension is available here:
