Requests that GDK create a OpenGL ES context instead of an OpenGL one,
if the platform and windowing system allows it.
The @context must not have been realized.
By default, GDK will attempt to automatically detect whether the
underlying GL implementation is OpenGL or OpenGL ES once the @context
is realized.
You should check the return value of gdk_gl_context_get_use_es() after
calling gdk_gl_context_realize() to decide whether to use the OpenGL or
OpenGL ES API, extensions, or shaders.
