Overview
This extension lets you mark chromium style GPU traces. Each trace can
specify both a category name and a trace name which will be associated
with the trace.
Each trace's beginning is marked by TraceBeginCHROMIUM and the end can
optionally be marked by TraceEndCHROMIUM. If the trace's end is not marked,
the trace will automatically end when the graphics context is destroyed.
Multiple traces can happen simultaneously, however traces act as a stack
and must be fully contained within one another. Therefore, you cannot
have overlapping traces.
Once a trace has been recorded, it is up to the application to decide
how the traces should be displayed.
New Tokens
None
New Procedures and Functions
void TraceBeginCHROMIUM(const char* category_name, const char* trace_name)

it lasts until the graphics context is destroyed or when TraceEndCHROMIUM
is called.
void TraceEndCHROMIUM()
Marks the last trace to end, this will signal the application to stop
tracing the previous trace.
Errors
