The new emoji assets (in sync with Android Lollipop) were slightly
smaller in size. Replacing with a corrected size.
Also update the font version to sync with Android again.
The bitmap emoji tools are extended to create GSUB rules for character
sequences. The images are renamed to code the character sequence in their
filenames. New images are created for ASCII digits and number sign. A new
script is added to add cmaps to the files for backward compatibility.
