OpenGL extension SGIX.async_pixel
This module customises the behaviour of the
OpenGL.raw.GL.SGIX.async_pixel to provide a more
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.
