This provides an interface for applications (and OpenGL-based tools) to

minimum/maximum values of all available counters. Counters are also
organized into groups.
Applications create "performance monitor" objects, select the counters
they want to track, and Begin/End monitoring, much like OpenGL's query
API. Multiple monitors can be in flight simultaneously.
We chose not to implement the similar GL_INTEL_performance_queries
extension because Intel has not bothered to publish a specification in
the OpenGL registry.
performance_monitor.c seems to be missing.
Yikes. The .c, .h, and .xml file were all missing. Apparently I forgot
to re-add all the new files after resetting to split a patch.
I've resent a version that actually has everything. Sorry for the trouble.
