emoji colorized gyphs

Hi all,

With my team we are currently thinking of using freetype for one of our 
future project where we would like to use emoji colorized glyphs.

I have seen that this support has been added to version 2.10.0 of 
Freetype but I still have some issues to use it in my code(which is 
correctly working with other type of font files). I am probably not 
using the correct FT_xxx function and this leads to a segmentation fault 
when I tried to decode the font file.

I have some questions then:

1\ Can you point me to a public font file that you used to do your 
implementation of that feature?

2\ Do you have an simple example of code that I could use as a starting 
point.

Thanks for your support, and by the way thanks for that excellent 
software library.

Regards

Anthony
