set_style, landscape, systems, legends, clegends
set the detailed style of the current drawing. The arguments
are all inputs, having the same meanings as for get_style (which
see). All arguments are required, so you may need to call
get_style as a starting point, if you only want to make a few
changes. See the Gist/work.gs and the other .gs files for
examples of reasonable values to choose.
Calling set_style destroys anything that was plotted in the
window, like the style= keyword of the window command.
