9431bb9640 Lookup glyph from color emoji font before and after ZWJ. 
Unicode recommends that the zwj sequences should be emoji presentation
even if they don't have the proper U+FE0F. Thus always lookup the glyph
for the code point before and after zwj as if they have a U+FE0F
variation selector.

369d2d44cb Select emoji font based on variation selectors. 
If U+FE0E is appended to the emoji code point, the glyph should have a
text presentation.
On the other hand, if U+FE0F is appended to the emoji code point, the
glyph should have an emoji presentation.
