Subject: gles: Add support for GLES tracing to egltrace
X-Git-Tag: 2.0_alpha^2~484
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5b7584ebd8d90155b717c8c6fa5ed7ea025d7804;p=tools%2Fapitrace.git

gles: Add support for GLES tracing to egltrace

Override GLES entrypoints and set the tracer context's profile when
eglMakeCurrent is called.  This allows egltrace to trace GLES apps.
