[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.

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.

Octicons.

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.

Lekton was the only font that selected TYPO but we forced it to WIN,
because not all glyphs fit into the values from TYPO.

span multiple lines. So I guess we should revert that change and render

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

The filenames of the patched fonts are rather ... unique:
- they contain blanks to separate name parts
- they do not separate name and style/weight
This is in part due to history reasons, because the names were not
parsed at all and just some suffix added.
Example (contrived):
Victor Mono Nerd Font Propo Bold.ttf
Normally font file names would be:
VictorMonoNerdFontPropo-Bold.ttf
We ourselves relied in part on that naming scheme, but do not follow it.
There are a lot powerline fonts out there that all add blanks to the
filename.
Some filename recommendation can be found in [1].
[how]
The filename is now always constructed directly from name ID 16
and name ID 17. If one of them is empty ID 1 and ID 2 are used as
fallback, as customary.
ID 16 (ID 1) and ID 17 (ID 2) are separated by a hyphen.
The result is that in can differ from the fontname (ID 6) and uses
always the longest most readable name parts.

OriginalName Nerd Font Complete Mono
OriginalName Nerd Font plus Weather Mono
But the 'Mono' part is quite important, but this scheme will put it in a
place where it is easily out of view or has been removed (to keep the
name short).
This truncation is especially bad on Windows Compatiple and when the
user installs both the 'Nerd Font' and the 'Nerd Font Mono':
SomeVeryLongFontName Nerd Font Complete
SomeVeryLongFontName Nerd Font Complete Mono

Any non-monospaced font will not be be patched, the patcher crashes.
[how]
This must have happened when the box drawing characters rescaling
feature has been disabled. The default value (False) is not always set.
The box drawing patch has the ability to rescale existing box glyphs.
That used to be done when all box glyphs are already existing in the
source font. We do not patch in a new glyph set then, but we rescale the
existing glyphs to match the possibly new cell size.
But that feature is disabled and the attribute 'dont-copy' is never
utilized. It is disabled because some existing box sets are rather ...
sspecial in their overlap and can not be scaled as we would scale them.

One example is Windows notepad, that takes the xAvgCharWidth as base for
the cell size and draws the two-cell chars in a cell twice that size -
without any regard to glyph width.
[how]
These issue seems to be encountered rather seldom and only with some
obscure (grin) applications. There is also no good way to handle this
automatically. So we add a command line option that allows the user to
tweak the value after patched-font generation.
The option is called `--xavgcharwidth`:
* If not specified the behavior of the patcher does not change
* If just given the xAvgCharWidth is copied over from the source
* If a number is added that number is used as xAvgCharWidth
* If the number added is zero we will calculate the old style xAvgCharWidth

It does probably not make too much sense to add the box drawing glyphs
to proportional fonts. The boxes that are drawn need to be filled with
some text, and if that does not have monospaced property the box will
always look ugly and not fit and change when the font is changed.
[how]
Make the fact if we detect a source font as monospaced or not a property
of the patcher object.
Always determine that property (before we just determined it when the
target font should have monospaced behavior).

Normally the 'cell' size should not change on patching. If the 'cell'
size does not change we do not need to rescale the box glyphs. They
probably worked before, they work the same afterwards.
Another reason to disable this is Cascadia Code. It has box drawing
glyphs that extend for more up then the normal cell. If we rescale that
to fit a probably new cell size we get a 'midline' that is too low
(because the upper stems are longer).

Some few glyphs get a wrong left side bearing in `Nerd Font`:
E0C2: -1230
E0C5: -857
E0C7: -667

These are the powerline glyphs which are right aligned and have overlap
and a target width of 2 cells wide.

To simplify the code add a new function that decides if a symbol shall

That function is then used where we had explicit tests already.
Use the function also in the overlap correction code, such that the
overlap is corrected for the right cell occupancy of the concrete glyph.

The box drawing glyphs (center aligned) and some Powerline glyphs (that

Affected are all box drawing glyphs (e.g. 2548) and some Powerline
glyphs (i.e. E0B2, E0B6, E0C5, E0C7, and E0D4).
[how]
The box drawing glyphs are center aligned and have overlap. The code
does not correct the overlap (left bearing) but uses the default case of
'make the left bearing zero'. The code does just check left aligned
glyphs and not center aligned ones.
Add the correct overlap for center aligned glyphs (i.e. half the
overlap).
The Powerline glyphs are right aligned. Usually that works, because the
glyphs are created with the right size, so that no additional
manipulation is needed.
But if the glyph has a ratio limit the resulting size will be different.
We could in fact fix the size code, somehow, but that is rather
complicated, formula-wise. Instead we just scale these glyphs (which are
the 5 listed above) and shift them to the right position such that the
correct overlap results.
