[why]
The codicons have 3 obvious (from the name) pairs of regular and small
icons. The size difference is slight but visible.
When we maximize all individual icons the differences are mostly lost.
[how]
Put each pair into one ScaleGroup to keep their individual scaling.

[why]
The added heavy brackets are maximized within the cell size as all
normal other symbols. But in fact they should not be maximized but
rather be the size of 'normal brackets'.
Furthermore they are all scaled individually, making the size
differences less.
With some proportional fonts the brackets look tiny.
[how]
Introduce new y-padding parameter (because a negative overlap also acts
in x direction, what we do not want (and it distorts)).
Pad the brackets with 30% (15% top and 15% bottom).
This is used for all fonts (monospaced or not) so that the new glyphs
fit nicely with the existing ones. For some definitions of 'nicely', but
that is as good as we can get with automatism. It's not worse than
font-fallback.

[why]
When the Heavy Brackets are scaled we want them to be scaled according
to 'pa1!' (i.a. preserve-aspect, only-one-cell, scale-always).
This is not possible because the glyphs have a ScaleRule and that
always assumes pure 'pa' and nothing else.
[how]
When the first glyph of the group is encountered the group scaling is
determined. This now takes the stretch rule of THAT glyph (instead of
just 'pa') to prepare the scale of the complete group.
[why]
After changing something in the patch process it is unclear if all the
prepatched fonts will look ok later. It would be nice to produce one
font from each input font (and not the complete set of each of the faces
of that font) to have some hopefully representative example how symbols will
blend into the font.
[how]
Add a script with explicit list of representative fonts.
Evaluate the config.cfg and execute one patcher run.
Signed-off-by: Fini Jastrow <ulf.fini.jastrow@desy.de>
[why]
The config.cfg settings can be wrong if the to-be-patched font does not
set its own. The previous settings are never cleared, so that the flags
leak into the next font(s).
This is only relevant when the run is not parallel (i.e. no -j given) and
all fonts are patched sequentially in the same shell.
On parallel runs (like the release process) this is not a problem
because each patcher runs in its own subshell.

The CI process produces a different font than running the
generate-original-source script locally.
Several thing have been checked, to no avail, see #1227.
Turned out the affected SVGs all are somehow ... questionable in their
construction.
[how]
Open SVGs in inkscape, select all (points) and generate new, clean
outline with Path->Union.
Save as optimized SVG.
The (CI) created font file now looks good.
But the cause is still unknown, maybe some sub-library that is used has
changed? I have no clue. Meaning it runs ok locally seems to be no
guarantee it will look the same when run by the CI :-(

The Seti and Custom icons are smaller than in ancient Nerd Font versions
and can seem a bit flimsy. In fact we add about 25% of padding (12% left
and 12% right) to each icon, which seems a bit generous.
This does not show in Nerd Font Mono fonts, because the icons will be
rescaled there, but in the other fonts.

The Ubuntu Condensed font is special because it is designed to be not
part of the `Ubuntu` font family but a self standing `Ubuntu Condensed`
family with just one member.
We want the `Ubuntu Condensed` to be part of `Ubuntu`, as it is usual
for fonts with different widths.
The problem then arises that the width class in the font metadata is set
to 'Normal', while it has to be 'Condensed'. That fact does not become
apparent when the font is in its own one member family, but even there
it is wrong.
[how]
To keep all the other information in the font untouched we just directly
patch that one byte where the width-class is stored - and repair the
checksums afterwards. Nothing more.
The code to do this is the Font Tweaker code in font-patcher, just
copied here for one time use.

With Ubuntu-Regular the fi and fl ligatures are replaced by some font
awesome icons.
The problem is that the font uses the non-standard F001 and F002
codepoints as intermediate referencve to create the actual ligatures
that are at codepoints FB01 to FB04.
[how]
All the normal ligature codepoints (FB00-FB06) are added to the glyph
reference checker and codepoints that are referenced by these are not
patched.
This means that F001 and F002 stay on the original ligatures and the
Font Awesome icons are missing, but this can not be fixed automatically
and would need to 'rewrite' the references inside the font.

Fixes: 1213
Signed-off-by: Fini Jastrow <ulf.fini.jastrow@desy.de>
[why]
Some people, for example the `lsd` project, need an icon with a symlink
directory. That has been dropped by Octicons. Our repacking put some
unrelated bookmark icon on that codepoint; but even an empty glyph would
be not ideal.
[how]
Design a file-symlink-directory from file-symlink-file and
file-directory. In this way it fits nicely into the current design of
Octicons.
Sneak that into the unpacked Octicons archive.
Adapt mapping manually to keep as much as possible constant.

While the commit
7cda32651 font-patcher: Allow to specify custom symbolfont with absolute path
would have allowed to specify the custom glyph font with an absolute
path, it is in fact still not possible.
[how]
The file-exists checks also need to observe the absolute path.
[note]
Normally (with a relative path) the custom font is search for in the
ordinary glyphs directory - but that would mean people need to copy it
there.

[why]
When a user want to patch some glyph in, and at that position is already
a glyph, there is no way to overwrite it.
The reason is that --custom glyphs are always patched in --careful, and
there is no --not-careful option to override that.
[how]
Add glyphs via --custom always, except --careful has also been given.

[why]
If you add a custom icon it probably has to fit with the rest of the
font. So why should we patch it in completely unscaled?
[how]
Just scale the custom icon like all other icons at least.
If someone wants to add just a symbol or two and keep the glyphs exactly
(more or less) unscaled there are simpler ways than this patcher
script. I believe persons that are able to pre-scale the custom font are
also able to just patch it in. So this option is more for the generic
patching of extra glyphs but they need to be scaled somehow.

[why]
The Box Drawing glyphs need to be carefully scaled. This can not be done
if the glyphs are pulled in via font-fallback I guess.
As people may have the fontconfig set up in a way to prefer the Symbols
Only font these glyphs could overrule other box drawing glyphs that
might fit better.
I'm not really sure about this one, but the glyphs look rather bad
anyhow, because they end up in the 1:1 ascpect ratio cell of the Symbols
Only font.
[how]
Just turn the set off if we patch the Symbols Only font.
Need to swap around two subroutine calls for that; first detect if we
are patching the Symbols Only font (through the font metrics) and then
set the patch sets up.

Maybe it is not a good idea to always create the log file, as most
people will never look into it. The main reason for it was the
gotta-patch-em script so that one can check after lots of runs what the
details were.
[how]
Introduce parameter to --debug option.
0 = no debug output
1 = log to file only (previously always selected)
2 = log to stdout only
3 = log to file and stdout (previous default for --debug)
Just specifying --default equals now --debug 2.
The gotta-patch-em runs now with --debug 1.
