From: Ryan Zhang <mailto>
When the user selects GLES via '-display sdl,gl=es', we need to set
SDL_GL_CONTEXT_PROFILE_MASK to SDL_GL_CONTEXT_PROFILE_ES before
calling SDL_GL_CreateContext(). This ensures SDL_GL_LoadLibrary()
loads the correct GLES driver instead of the desktop OpenGL driver.
Fix the below issue: qemu-system-aarch64: /usr/src/debug/libepoxy
/1.5.10/src/dispatch_common.c:872: epoxy_get_proc_address: Assertion
`0 && "Couldn't find current GLX or EGL context.\n"' failed.
sdl2_gl_create_context() already sets the profile mask correctly for
ES mode, but the initial context created in sdl2_window_create() is
missing the same treatment.

matching opengl renderer")
