It would be great if Threepenny GUI supported the ability to draw dashed lines with the setLineDash function. See the following reference:

Contributor guide

Research direction
Investigate the Threepenny GUI Canvas module and add a new function `setLineDash` that maps to the JavaScript canvas context method of the same name. Consider accepting an array of numbers for the dash pattern.
