add emoji family for emoji clusters #56

Closed dfrg closed 4 months ago

dfrg commented 4 months ago

Quick and dirty fallback for emoji. This can be done more efficiently (and should be handled in fontique directly) but this should get us functioning emoji mapping for capable renderers.

Applying this on top of the tiny-skia example I get a blank space for the emoji (which is expected because the ColorPainter trait and associated function call aren't implemented):

On top of the swash example I get "interesting" output:

I'm assuming this is an issue with the example rather than this PR as it seems to selecting the correct font/glyph.

Is it meaningful to have a test for this?

It is meaningful but the structure of this file makes unit testing difficult. I filed an issue for refactoring at #57
