OpenGL ES Extension #56

This extension interacts with AMD_performance_monitor.

This extension introduces a global tracking mode in the performance
monitors. When enabled, the counters increment in all operations,
including all "housekeeping" operations such as resolves/clears and
operations performed by other concurrent applications. The normal
operation is to track only the application's own operations.

(1)  How do we filter operations from other applications?

RESOLVED: We don't. The user of this extension should be aware of the
consequences.

(2)  What should happen if the global mode is enabled or disabled while
     the performance monitors are in use?

RESOLVED: The results in this case are undefined.

Accepted by the <cap> parameter of Enable and Disable, and
IsEnabled, and by the <pname> parameter of GetBooleanv, GetIntegerv,
and GetFloatv:

    PERFMON_GLOBAL_MODE_QCOM                     0x8FA0

None.

Add this to the Performance Monitoring section that was added by
AMD_performance_monitor:

None

// Activate global performance monitor tracking
glEnable(GL_PERFMON_GLOBAL_MODE_QCOM);
