Make sure "print '-SX,Y' ..." doesn't round down a pixel. Bug # 35307.
The eps output from gnuplot and gl2ps each specify whole numbrer bboxs.
Modify ghostscript's resolution to ensure output size is correct. Also
adjust fontisize to compenstate for resolution change.
* __print_parse_opts__.m: Set ghostscript resolution to 72 to ensure all
bboxs have whole numbers. Add a scalefontsize variable to enable fontsize
to be compensated for change in resolution.
* print.m: Modify fontsize property value to compensate for change in
ghostscript resolution.
* __gnuplot_drawnow__.m: Increase precision for specified canvas size.
