Render pikchr in static outputs

[Nicholas Bollweg]

Elevator Pitch

Allow pikchr to be either rendered in-browser or as img or svg tags in various outputs.

There might also be the case for rendering syntax-highlighted pikchr source.

Motivation

This would make pickhr diagrams more useful in documentation.

Design Ideas

drawing pikchr:

• rendering in-browser
  • get the .wasm and a (new) .js into the document somehow and then rendering.
• rendering in python
  • getting pickhr more widely-installable and shelling out
  • using a wasm backend (probably wasmer-python)
    • this would be an optional dependency

highlighting pikchr:

• probably means a pygments lexer

[Nicholas Bollweg]

The emscripten-compiled .wasm doesn't work simply in wasmer. May proceed with getting it compiled for e.g. conda-forge.

This is now available on conda-forge as fossil-pikchr.
