    [xlib] Avoiding sending glyphs > XMaxRequestSize.

    XRenderAddGlyph() does not split its image data across multiple requests
    and so the glyph surface must be smaller than XMaxRequestSize or else
    the server will disconnect the client, causing "Fatal IO error 104".
    As this will require an extension to the XRender spec, we can work
    around the issue by using our fallbacks if we detect that the glyph will
    be too large for a single request.

    See bugs https://bugs.freedesktop.org/show_bug.cgi?id=4339 and
    http://bugs.freedesktop.org/show_bug.cgi?id=13266 for examples.
