Handwriting Input Testing

Handwriting.go contains functions used to read SVG files, generate and populate strokes, and draw the SVG file on the handwriting input.

Creating the handwriting input test SVG file

Any SVG editor can be used to create the handwriting input test SVG file, however, this file must be created using LineTo commands only. There are many online editors that specifically use LineTo commands only, or the Line tool can be used to create the file.
