OpenGL.GL.SGIX.async_pixel

OpenGL extension SGIX.async_pixel

This module customises the behaviour of the OpenGL.raw.GL.SGIX.async_pixel to provide a more Python-friendly API

Overview (from the spec)

This extension introduces a new asynchronous mode for texture download, pixel download and pixel readback commands. It allows programs to transfer textures or images between the host and the graphics accelerator in parallel with the execution of other graphics commands (possibly taking advantage of a secondary path to the graphics accelerator). It also allows programs to issue non-blocking pixel readback commands that return immediately after they are issued so that the program can issue other commands while the readback takes place.

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