Sometimes a user might want to keep the original name.
This is escpecially true as Visual Studio seems to look at the font
names directly and enables special handling for 'Cascadia Code'.
Users might want to self-patch without renaming.
[how]
Add additional value to makegroups option.
That option should probably be renamed into 'naming scheme' or
something, as it is not really a fitting description of what it does.

f84a4a46d font-patcher: Add Codicons scale list
Signed-off-by: Fini Jastrow <ulf.fini.jastrow@desy.de>
Codicons: Maximise all circles
[why]
The scaling works okay for `Nerd Font Mono` fonts, but not for `Nerd Font`
fonts. The later have 'unexpected' left side bearing, which looks even
more out of place because the width is unrelated to the advance width
and might place the majority of the glyph into the next cell.
[how]
In fact we do not want scaling and shifting to be uniform for all glyphs
but the intend was to get the scaling from the biggest (full size)
circle and all the smaller ones would be proportionally smaller.
So we add a new Scale grouping that just takes the scale and the
vertical shift of the combined boundingbox, but individually calculates
the horizontal shift.

Patching CartographCF-Bold.ttf creates this naming:
Family (ID 1) : CartographF Nerd Font Condensed
SubFamily (ID 2) : Bold
Fullname (ID 4) : CartographF Nerd Font Condensed Bold
PSN (ID 6) : CartographFNF-CondensedBold
PrefFamily (ID 16) : CartographF Nerd Font
PrefStyles (ID 17) : Condensed Bold
CartographF Nerd Font Condensed Bold
\===> 'CartographFNerdFont-CondensedBold.ttf'
[how]
The font-patcher historically used the file name of the to-be-patched
font to come up with the new name. When the FontnameParser has been
developed that mechanics has been copied at least for fallback. The
earliest tests compared old and new naming with all the filenames.
Later, when the FontnameParser has been used to really apply name
changes it has always based the parsing on the Fullname or the PSname,
because they really hold the information (or at least should hold);
while the filename might be completely random.
Still code the dealt with specific problems in FILEnames prevailed. The
Ubuntu font for example has a file name like 'Ubuntu-C.ttf', and we
needed to convert the C to Condensed.
As that requirement vanished we can drop all the code that has been
added specifically only for parsing the Ubuntu font filenames.
Side note: USUALLY font filenames should be roughly equal to the PSname.

that grouping fails.
This affects DejaVu on Putty.

For RIBBI grouping only the classic bits are considered. That means that
for fonts that have Oblique instead of Italic (and not additionally) we
need to set the ITALIC bit and the OBLIQUE bit. This has been
overlooked.

[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.
Fixes: #1229

[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]
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.

If you add a custom icon it probably has to fit with the rest of the

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.

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.

Lekton has a too wide line spacing.
Lekton was the only font that selected TYPO but we forced it to WIN,

span multiple lines. So I guess we should revert that change and render
Lekton with the TYPO values.

Because we do not know if a complete family of fonts has an italic face
we must always assume it does. To get clean RIBBI families in ID1/2 we
create a different family for the oblique slant.
But that is not needed if the font does not have an italic slant, but
just an oblique one (like Bitstream Vera and descendants).
[how]
Add new command line option for font-patcher that specifies if the
family of fonts should be patched under the assumption that there might
be an italic face (default), or if we are sure there is none (and we can
leave oblique in the RIBBI group).
This is then applied to the config.cfg files.

We want to keep "Nerd Font" in the font name if possible and instead
shorten the weight part with accepted abbreviations. But these abbrevs
are hard to read and sometimes a more mild abbreviating might be
sufficient to get the desired name length.
[how]
Introduce a new shortening method for the weight parts of a family name.
It takes a longer word (often un-shortened) when a weight stands on its
own, but when a modifier is used together with the weight the more
aggressive two-letter abbreviations are used.
That new shortening method becomes the default and all the functions get
a new parameter to enforce completely aggressive shortening, i.e. always
use the shortest possible form.
The new way to shorten is exposed all the way out to the font-patcher
user who can select the shortening method as parameter to the
--makegroups option. That option is undocumented because I expect some
changes later on, still.

[why]
The option --makegroups shortens the name suffix and the styles
rigorously. That is needed for fonts with long names and/or long style
descriptions.
But some simple font would not need that. With the option we can adjust
the amount of shortening to fit the specific font (family).
Unfortunately we can not automatically detect that, because the
font-patcher script can not assume anything about a complete family as
every font file is patched individually.
[how]
Add optional numeric parameter to option '--makegroups'.
The values can be:
0 - turned off, use old naming scheme
1 - turned on, shortening 'Bold' to 'Bd'
2 - turned on, shortening 'Nerd Font' to 'NF'
3 - turned on, shortening 'Nerd Font' to 'NF' and 'Bold' to 'Bd'
4 - turned on, no shortening
If --makegroups is not specified this is the same as '--makegroups 0'.
If --makegroups is specified without number that means '--makegroups 3'.
[note]
The argparser module takes the last specified parameter as the one to
use: If you specify --makegroups multiple times only the last one will
be used.
This can be used for gotta-patch-em-all. Per default it (will) specify
--makegroups 3. But via config.cfg we can specify a font centric other
number for individual fonts. The config.cfg values are added later in
the command line, so they take precedence.

This just drops the 'windows compatibility' options in association with

not working correctly. But it is easier to do this in smaller steps.
