There have been past discussions about this.
I think the best approach suggested so far is to add "dashtype" as a
property in struct lp_style_type, and track it as a regular line
property along with line width, line color, point type, point style, and so on.

Most terminals specify dash pattern by an array of lengths; successive
array elements control the length of the first line segment, the length of
the first gap, the length of the second line segment, the length of the
second gap, and so on. "dashlength" is applied as a multiplier for these
lengths.
