 Revision 1.14  2005/12/07 22:01:11  jiaox
 Made the line types ( thickness color dash style) consistent among motif,
 postscript and png devices. Added device arguments dashes and linetypetable
 for these devices to draw lines with user defined line styles.

 Revision 1.13  2005/11/04 22:46:45  soliday
 Updated code to be compiled by a 64 bit processor.

 Revision 1.12  2005/03/22 03:33:54  soliday
 Made various changes including fixing a problem with the intensity bar
 colors. Also changed png and ps default colors so they are all
 the same as motif.

 Revision 1.11  2003/11/20 16:03:05  soliday
 Added sendCoordinates to the list of device functions.

 Revision 1.10  2002/11/14 03:03:15  borland
 To fix problems with building mpl_motif:
 Moved SDDS_ReadLineColorTable from sddsplot.c to graphics.c.
 Moved LINE_COLOR_TABLE structure definition from sddsplot.h to
 graphics.h.

 Revision 1.9  2001/06/04 20:03:08  soliday
 Made some changes that only affect sddscontour.

 Revision 1.8  2000/06/07 20:08:10  soliday
 Added line_color and add_color to termentry

 Revision 1.7  2000/04/27 19:26:35  soliday
 Now support line thickness.

 Revision 1.6  1999/07/22 18:34:50  soliday
 Added WIN32 support

 Revision 1.5  1999/06/03 16:06:54  soliday
 Removed compiler warnings under linux.

 Revision 1.4  1998/12/22 16:02:35  borland
 New character scaling algorithm for all labels.  Considerable changes
 to psymbol routine that draws characters and returns the size of
 strings.

 Revision 1.3  1998/08/25 15:05:26  borland
 New version with major changes to allow multiple scales on x and y axes.

 * Revision 1.2  1995/09/05  21:09:23  saunders
 * First test release of the SDDS1.5 package.
