zero-width chars are ignored if they're at col 0
...
This can cause a crash, and is impossible since zero-width chars are
always attached to a prior character. Word-wrapping doesn't come into
play here because this check happens prior to the wrapping.

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.

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.
