'''OpenGL extension GREMEDY.string_marker
This module customises the behaviour of the
OpenGL.raw.GL.GREMEDY.string_marker to provide a more
Python-friendly API
Overview (from thespec import
This extension defines a mechanism to insert textual markers into
the OpenGL stream.
When debugging or profiling an OpenGL application some of the most
important tools are stream loggers, which just output a list of the
called OpenGL commands, and profilers, which show at which points
the pipeline is bottlenecked for a given part of the frame. The
problem in using these is that there is a definite loss of
information between the application and the used debugger/profiler.
The application generally has a pretty good idea what is rendered
when (e.g. rendering background, landscape, building, players,
particle effects, bullets etc.), but the debugger/profiler only
sees the OpenGL stream. To analyze the stream developers have to
guess what is done when by following the program code and the log
output in parallel, which can get difficult for systems that
restructure their internal pipeline or do lazy changes.
This extension is really only useful for these debuggers and
profilers, and not for actual drivers. In fact, it is not expected
that any standard driver would ever implement this extension. The
main point of having this extension is to allow applications to have a
clean way of accessing this functionality only when they are run
under the control of a debugger/profiler, without having to
recompile or change the application source code.
The official definition of this extension is available here:
