Requests that GDK create an OpenGL ES context instead of an OpenGL one.
Not all platforms support OpenGL ES.
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 [method@Gdk.GLContext.get_use_es]
after calling [method@Gdk.GLContext.realize] to decide whether to use
the OpenGL or OpenGL ES API, extensions, or shaders.
