/**
* @file
* @brief Test EGL_CONTEXT_OPENGL_DEBUG_BIT_KHR.
*
* Call eglCreateContext with EGL_CONTEXT_FLAGS_KHR=EGL_CONTEXT_OPENGL_BIT_KHR.
* If context creation succeeds, then verify the context is really a debug
* context by verifying GL_CONTEXT_FLAGS contains GL_CONTEXT_FLAG_DEBUG_BIT.
* If context creation fails, then verify that EGL_BAD_MATCH is emitted.
*
* A commandline argument specifies which OpenGL API to test.
*
* From version 15 of the EGL_KHR_create_context spec:
*
* If the EGL_CONTEXT_OPENGL_DEBUG_BIT_KHR flag bit is set in
* EGL_CONTEXT_FLAGS_KHR, then a <debug context> will be created.
* [...] This bit is supported for
* OpenGL and OpenGL ES contexts.
*
* and
*
* If <config> does not support a client API context compatible
* with the requested API major and minor version, context flags,
* and context reset notification behavior (for client API types
* where these attributes are supported), then an EGL_BAD_MATCH
* error is generated.
