Pikchr Block

This Gutenberg block renders Pikchr code to SVG.

Like the markdown block there are security considerations with allowing SVG to be embedded in a post, so this block will only work when the current user has the unfiltered_html capability. This is generally just admins of the site.

The Pikchr code is rendered using a WASM compiled version of the C library. The source for the C library is included in this repo, for the purposes of recompilation, and includes the Zero-Clause BSD license. Please see the Pikchr site for any further information.
