Update of /cvsroot/plplot/plplot/sys/dos/djgpp/src
In directory usw-pr-cvs1:/tmp/cvs-serv30491
Updated version of the GNUSVGA driver to support DJGPP V2.0+ and GRX23.
New driver adds support for double buffering, mouse events, XOR mode, locate
mode, and a cross hair mode, plus optional support for screen dumping the
image to bitmaps, TIFFs or JPEGS. The driver also fixes up problems with the
key detection, switching to text mode and back to graphics mode, and
different coloured backgrounds. Three new dirvers are supported by the
driver that add the ability to plot straight to bitmaps, TIFFs or JPEGs.
