/**
** to_sunview.c: Sunview previewer for hp2xx
**
** 92/01/28 V 1.00a HWW Derived from project njm
** 92/05/19 V 1.00b HWW Abort if color mode
** 92/05/25 V 1.10a HWW Colors supported
** 93/01/06 V 1.10b HWW "xx" added in front of color names
**
** NOTE: Sunview itself is a dying standard (to be replaced by OpenLook
** and/or X11). Therefore, I won't continue to maintain this file.
** In hp2xx's next release this file will appear in ../extras.
** Please use to_x11.c for future previewing on Suns.
