* There are two different tracing methods:
* 1. libs/EGL/trace.cpp: Traces all functions to logcat.
* There are three different tracing methods:
* 1. libs/EGL/trace.cpp: Traces all functions to systrace.
* To enable:
* - set system property "debug.egl.trace" to "systrace" to trace all apps.
* 2. libs/EGL/trace.cpp: Logs a stack trace for GL errors after each function call.
* To enable:
* - set system property "debug.egl.trace" to "error" to trace all apps.
* 3. libs/EGL/trace.cpp: Traces all functions to logcat.
* To enable:
* - set system property "debug.egl.trace" to 1 to trace all apps.
* - or call setGLTraceLevel(1) from an app to enable tracing for that app.
* 2. libs/GLES_trace: Traces all functions via protobuf to host.
* 4. libs/GLES_trace: Traces all functions via protobuf to host.
* To enable:
* - set system property "debug.egl.debug_proc" to the application name.
* - or call setGLDebugLevel(1) from the app.
