print/ghostscript8 gtk support

[Hiroki Sato]

Hi,

 Can anyone try a patch for print/ghostscript8 and let me know if
 there is something wrong in your desktop?  The patch can be found at:

  http://people.allbsd.org/~hrs/FreeBSD/ghostscript8_nogtk_20100808.diff

 This patch removes GTK+ dependency from GhostScript by default. The
 difference before and after applying the patch is that "gsx
 -sDEVICE=display" no longer generates display window (via GTK).

 I guess this is not directly related to GNOME itself, but I am
 interested in whether this change is safe in standard GNOME
 environment; some applications may use the "display" device as a
 backend for postscript rendering.  Thank you.
