font: web canvas face has to render to check presentation for cp
...
Since we have no way to detect our presentation (text/emoji), we need to
actually render the glyph that is being requested to double-check that
the glyph matches our supported presentation.
We do this because the browser will render fallback fonts for a glyph if
it can't find one in the named font.

things work incrementally and its a pretty cool thing to have as a wasm

font: when resizing a glyph, scale metrics by same ratio
...
We rely on the top/left offset to position the glyph properly. When we
were resizing, we weren't properly recalculating this offset which led
to some glyphs slightly (or majorly) off depending on how much they
resized.
