Use consistent gnuplot toolkit font syntax allow SVG fractional font size (bug #53737)
* print.m: Document the cgm and eepic terminals (gnuplot only).
* __gnuplot_print__.m: Condition "background" option on several of the terminal
types which otherwise would produce a gnuplot warning. Add terminal type
cases "cgm" and "latex" to the list of generic plotting formats.
(font_spec): Use the 'font "<name>,<size>"' format in almost all cases, which
has been made more consistent in recent gnuplot versions. Remove code that
rounds the SVG font size.
* __print_parse_opts__.m: Add to the dev_list "canvas", "cgm", "latex" and
"eepic" and correspondingly to the suffixes "js", "cgm", "tex" and "tex".
