LINETYPE=<list_of_device-dependent_control_words>
(in PLOT operation) corresponds to PEN (PEN?) but gives the default
setting for plotting lines and curves.
Examples:
LINETYPE=[line_width(0.48)][line_color(0.5)] (in PostScript plotting)
LINETYPE=[line_color(-1)][line_type(4)]
FILL(-1)=0.2,0,1,0 (giving CMYK values for [line_color(-1)])
[line_type(x)] (in GPLOT and PLOT) specifies the type of the line
to be drawn. The alternatives are
[line_type(0)] solid line (in GPLOT round endcups)
[line_type(1)] long dash
[line_type(2)] dotted
[line_type(3)] dash dotted
[line_type(4)] medium dash
[line_type(5)] dash with two dots
[line_type(6)] short dash
[line_type(7)] dash with three dots
[line_type(8)] solid line without round end cups (GPLOT only)
