Snap!-tools is a collection of custom blocks and extensions built for the
Snap! programming language. Most of these rely on the
reportJSFunction block which allows native JS to be executed within Snap!.
The easiest way to use these blocks is to download the repo and then use the "Import" menu within Snap!.
See text-stamping.xml for this block. This allows native text stamping on the
stage. It uses a monospace font and will use the current pen color and stamp
text at the same angle as the sprite. If the pen is down, the text appears underlined.
