    gdk/win32/gdkglcontext-win32.c: Fix think'o
    
    Trying to test whether a GdkGLContext is a GLES context when it is NULL
    is quite dumb, and we are actually asking for the assertion
    that the GDKGLContext is NULL :| D'oh...
    
    Instead, see whether we have set up an EGL display, which should always
    be present when EGL is being used (and otherwise not when WGL is used),
    and determine which way we should make no GL/EGL context current.
