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.

We don't need the Atlas API for wasm at all, but its a good way to test
things work incrementally and its a pretty cool thing to have as a wasm
library really.
