It's time to have/document a NodeJS/browser API for SVG Tiler. Example applications:

  • Generating a drawing (spreadsheet) algorithmically.
  • Generating an animation where each frame is a slight tweak to a previous frame, and you want to output SVG or PNG of each, then assemble into an animated GIF.
  • SVG Tiler GUI

At the minimum, we want to load some mappings (from data or files), and apply them to drawings (in data or in files). In particular, need to formalize the internal mapping and drawing formats (which shouldn't be difficult).

At this point (Oct. 28, 2022), this is mainly a documentation issue, as the APIs have been substantially improved.

Rewrite to generalize mappings (fix #13) and global cache (fix #50)
bfdc132 
* Support mapping defined by `Map` or `WeakMap`
* All function mappings are now automatically dynamic;
  no need to wrap in a second layer of function.
* Can force old static behavior (for efficiency)
  via `svgtiler.static` wrapper, cached at `Mapping` level.
* Function mappings get `context` second argument in addition to `this`.
* `Context` object now shared throughout each drawing
  (so you could store extra drawing-specific data there).
* API change: `Context` no longer has `symbols`, `symbol`, `data`,
  `filename`, or `subname` attributes.  For the latter three,
  use `drawing.data`, `drawing.filename`, or `drawing.subname`.
* API change: No more `Symbol`, `StaticSymbol`, or `DynamicSymbol` class
  (in particular, there was a name conflict with JS's `Symbol`)
* API change: `Input` constructor supports direct loading of data
  (for easy manual creation) or immediate parsing of file data,
  as well as option setting.  This will help with #34.
* New `Tile` class represents an expanded (and possibly parsed)
  tile `<symbol>` (roughly what `Symbol` was before).
* Tile caching/deduplication now within the renderer, not by `Symbol`
  (fix #50), enabling re-use when multiple symbols expand to the same SVG.
* Fix: Don't fill in `<image>` `width`/`height` when both already set.
* Fix: Use `hasOwnProperty` and `Set`s to avoid accidentally matching
  e.g. `toString`.
