mupdf-gl port warnings shown when using mupdf-gl to display a pdf file

[Kenneth Wolcott]

Hi;

  I recently installed the mupdf port.  The pdf output looks great,
but a nit: the following warnings are generated when using mupdf-gl to
display a pdf file.

warning: This version of MuPDF has been built WITHOUT clipboard or
unicode input support!
warning: Please file a complaint with your friendly local distribution manager.

Thanks,
Ken Wolcott
