'''OpenGL extension SGIX.async
This module customises the behaviour of the
OpenGL.raw.GL.SGIX.async to provide a more
Python-friendly API
Overview (from the spec)
This extension provides a framework for asynchronous OpenGL
commands. It also provides commands allowing a program to wait
for the completion of asynchronous commands.
Asynchronous commands have two properties:
1) Asynchronous commands are non-blocking. For example, an
asynchronous ReadPixels command returns control to the program
immediately rather than blocking until the command completes.
This property allows the program to issue other OpenGL commands in
parallel with the execution of commands that normally block.
2) Asynchronous commands may complete out-of-order with respect to
other OpenGL commands. For example, an asynchronous TexImage
command may complete after subsequent OpenGL commands issued by
the program rather than maintaining the normal serial order of the
OpenGL command stream. This property allows the graphics
accelerator to execute asynchronous commands in parallel with the
normal command stream, for instance using a secondary path to
transfer data from or to the host, without doing any dependency
checking.
Programs that issue asynchronous commands must also be able to
determine when the commands have completed. The completion status
may be needed so that results can be retrieved (e.g. the image
data from a ReadPixels command) or so that dependent commands can
be issued (e.g. drawing commands that use texture data downloaded
by an earlier asynchronous command). This extension provides
fine-grain control over asynchronous commands by introducing a
mechanism for determining the status of individual commands.
Each invocation of an asynchronous command is associated with an
integer called a "marker." A program specifies a marker before it
issues an asynchronous command. The program may later issue a
command to query if any asynchronous commands have completed. The
query commands return a marker to identify the command that
completed. This extension provides both blocking and non-blocking
query commands.
This extension does not define any asynchronous commands.
See SGIX_async_pixel for the asynchronous pixel commands.
