    gskrenderer.c: Default to the GL renderer on Windows too
    
    Since we have now made the Win32 GL contexts share the global context as
    the other backends have, we are more ready to use the GL renderer by
    default on Windows as well.
    
    Note that currently we can only enable this when not running on
    OpenGL/ES as the OpenGL/ES shaders are not ready at this point, and the
    OpenGL/ES support that we have from libANGLE does not support full
    desktop OpenGL operations.
