Subject: [PATCH] I discovered that for large designs, running DBWredisplay
 will take significant amounts of time even though there is no display to
 receive the result.  However, the "suspendall" command only works if a window
 exists.  The obvious solution is to set GrDisplayStatus to DISPLAY_SUSPEND
 whenever magic is run with the "-dnull" option. This should help speed up a
 lot of scripts, in particular where designs are large.
