From: Grigori Goronzy <g...@chown.ath.cx>
This test verifies context creation with the
EGL_KHR_create_context_no_error extension, which includes interaction
with debug and robustness flags. The test also verifies that the
KHR_no_error mode is successfully enabled with a check of context
flags and glGetError() behavior.
Both GL 2.0 and GLES2 are tested.
