Use .ttx as input for emoji_builder.py Originally the .ttx generated by add_glyphs.py was compiled to a .ttf file so it could be fed to emoji_builder.py. Now we can feed it a .ttx file and remove the compile step. This way the original glyph names are preserved and we can start adding PNGs for the components.
