This updates the svg, png, and html resources from behdad/region-flags.
It also updates the LICENSE (COPYING) and README.md files from there.
Formerly our copy contained only a few subregion flags, but this change
adds them all from upstream.
Also formerly we explicitly used symlinks in our data for flags that
are the same as other country flags. Now however we just use the
upstream data. Note that the emoji_aliases.txt file will still
cause the font to only have one copy of these.
Note this also deletes the copy of IC.png that somehow had found its
way into the region-flags directory.
Use big glyph metrics to support vertical text rendering
Clients who want to identify sequences in text that have image files
would like to use the file names to identify these sequences, and
would like to identify canonical sequences using this method.
Add an option to the add_aliases tool to also create aliases using
the canonical names where they differ from the file names.
Our file naming omits the emoji presentation selector character, so
the image files by default do not include it. This provides a means
to restore that.
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.
Currently `verbosity` is an undefined name and line 201 will raise a `NameError` when executed. The only other place in this repo where `verbosity` is defined is as a function parameter to [do_generate_test_html()](5e1808fbbe/generate_test_html.py (L28)) with a default value of `verbosity=1`.
Someone who really understands the functioning of this code should __carefully review this change before merging it__. My sense is that this approach is better than raising a NameError but perhaps I am all wet.
In some places `build_svg_dir()` the variable is `flag_dir` (singular) and in others `flags_dir` (plural). Settled on plural everywhere to match the function parameter name.
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.
This also deletes the svg images that are 'aliases' of existing images
according to our alias table, and the few flags (the flag data is not
sourced in the same way).
When building the font, images are composited onto a slightly
rectangular canvas that's 4 pixels wider on the left and right.
The thumbnails though are required to be 72x72, i.e. square.
In order that they look the intended size we need to crop off
the margins that were added earlier.
Same problem that we ran into previously with the emoji font--
imagemagick takes RGBA that contain only grayscale and converts
to grayscale with alpha, but although it can display these ok,
chrome can't. So force it to generate RGBA output.
