Unicode has provided guidance on how flags such as the rainbow flag can
be implemented using exiting Unicode characters.

This update adds rendering support for the rainbow and pirate flags as
well as visual updates to the ‘back’, ‘soon’, ‘top’, ‘end’, and ’on’
emojis.
This adds the assets for the 72 new emojis from the Unicode 9.0 spec as
well as modifications to the bread, kaaba, and man in business suit
levitating emojis.
