Choosing emojis graphically is the popular way of choosing them, so
Emacs should have such a method.  If you don't want to use that,
nobody's forcing you -- use the method that displays with names instead.

It doesn't make sense in general, but for emojis you're unlikely to have
many separate fonts that cover different sets of emojis.  So once we've
established that you have an emoji font, we don't have to try to keep
loading fonts for the emojis that this font doesn't have.

The slowness is linear with the number of emojis that we don't have a
font for.
