The attached patch does the following for the X11 and Windows platforms, the only ones where SDL attempts to use context_create_es_profile:
- Adds SDL_HINT_OPENGL_ES_DRIVER by which the application can
say to use the OpenGL ES driver & EGL rather than the Open GL
driver. (For bug #2570)
- Adds code to {WIN,X11}_GL_InitExtensions to determine the maximum
OpenGL ES version supported by the OpenGL driver (for bug #3145)
- Modifies the test that determines whether to use the OpenGL
driver or the real OpenGL ES driver to take into account the
hint, the requested and supported ES version and whether ES 1.X
is being requested. (For bug #2570 & bug #3145)
- Enables the testgles2 test for __WINDOWS__ and __LINUX__ and adds
the test to the VisualC projects.
With the fix in place I have run testdraw2, testgl and testgles2 without any issues and have run my own apps that use OpenGL, OpenGL ES 3 and OpenGL ES 1.1.
These are test programs for the SDL library:
checkkeys Watch the key events to check the keyboard
loopwave Audio test -- loop playing a WAV file
loopwavequeue Audio test -- loop playing a WAV file with SDL_QueueAudio
testaudioinfo Lists audio device capabilities
testerror Tests multi-threaded error handling
testfile Tests RWops layer
testgl2 A very simple example of using OpenGL with SDL
testiconv Tests international string conversion
testjoystick List joysticks and watch joystick events
testkeys List the available keyboard keys
testloadso Tests the loadable library layer
testlock Hacked up test of multi-threading and locking
testmultiaudio Tests using several audio devices
testoverlay2 Tests the overlay flickering/scaling during playback.
testplatform Tests types, endianness and cpu capabilities
testsem Tests SDL's semaphore implementation
testshape Tests shaped windows
testsprite2 Example of fast sprite movement on the screen
testthread Hacked up test of multi-threading
testtimer Test the timer facilities
testver Check the version and dynamic loading and endianness
testwm2 Test window manager -- title, icon, events
torturethread Simple test for thread creation/destruction
controllermap Useful to generate Game Controller API compatible maps
