* ## Excalidraw and SVG
* 2022-04-16 - @thfrei
*
* Known issues:
* - excalidraw-to-svg (node.js) does not render any hand drawn (freedraw) paths. There is an issue with
* Path2D object not present in node-canvas library used by jsdom. (See Trilium PR for samples and other issues
* in respective library. Link will be added later). Related links:
* - https://github.com/Automattic/node-canvas/pull/2013
* - https://github.com/google/canvas-5-polyfill
* - https://github.com/Automattic/node-canvas/issues/1116
* - https://www.npmjs.com/package/path2d-polyfill
* - excalidraw-to-svg (node.js) takes quite some time to load an image (1-2s)
* - excalidraw-utils (browser) does render freedraw, however NOT freedraw with background
*
* Due to this issues, we opt to use **only excalidraw in the frontend**. Upon saving, we will also get the SVG
* output from the live excalidraw instance. We will save this **SVG side by side the native excalidraw format
* in the trilium note**.
*
* Pro: we will combat bit-rot. Showing the SVG will be very fast, since it is already rendered.
* Con: The note will get bigger (maybe +30%?), we will generate more bandwith.
* (However, using trilium desktop instance, does not care too much about bandwidth. Size increase is probably
* acceptable, as a trade off.)
