-/**
- * This fetch function is adapted from a `loadImage` function
- * credited to Parziphal, Feb 13, 2017.
- * https://stackoverflow.com/a/42196770
- *
- * The callback is generally run with the loading progress as a decimal 0-1.
- * However, if it's not possible to compute the progress ration (which might
- * only become apparent after a progress amount *has* been sent!),
- * the callback will be run with the value -1.
- *
- * The return promise resolves to a manually instantiated Response object
- * which generally behaves the same as a normal fetch response; access headers,
- * text, blob, arrayBuffer as usual. Accordingly, non-200 responses do *not*
- * reject the prmoise, so be sure to check the response status yourself.
