A previous commit intended to remove the old PNGS and just leave the
new ones, but neglected to add the new ones resulting in the deletion
of all the PNGs. Um... oops.
The update to the new design accidentally left some old images. The new
design doesn't include resources for images we alias, and when the
directory was updated I forgot to remove the images corresponding to the
aliases.
We currently name the mixed-gender 'kiss' and 'couple with heart'
images after the single-codepoint sequences. But aliasing maps
the single codepoint sequence to the gendered sequence, not the
reverse. As a result the build doesn't create ligatures for the
gendered sequences, since it thinks the image doesn't exist.
Fix this to use the gendered-sequence-names for these images, and
let aliasing work as intended. This follows the convention we've
adopted of letting the name more completely describe the image
contents, and defining how to represent less-specific sequences
using aliasing rather than baking these decisions into each image
name.
We've been inconsistent about use of the variation selector in image names,
and it's cleaner if we just consistently drop it. We use the unicode data
for the full unicode strings for these names now so we don't need it in
the image data.
Updates many existing emoji, and adds new emoji, including zwj
sequences for blended families. The updated emoji have not been
optimized or resized, run them through the makefile to get ones
similar to the previous existing ones. Not all updated emoji are new
renderings.
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.
