Hershey fonts for OpenSCAD

The standard OpenSCAD fonts work well for a simple extrusion 3D profile. But what if you want a different 3D profile, e.g., you want text that looks like it's been machined with a V-shaped bit, or text that is rounded in 3D?

This library includes the ASCII portions of the Hershey vector fonts, and draws text using whatever convex shape you specify. For instance, you can do rounded text via:

use ;
drawHersheyFont("Hello, OpenSCAD!", font="Script") sphere(r=2,$fn=16);
