If the font has contradicting baseline to baseline metrics the patcher
tries to find a sane value and use that. That automatism gets it right
in most cases, but there might be fonts where the user wants a different
metric to be used.
At the moment the use would need to use `font-line` to adjust the
metrics, which is not very convenient.

Add option to select one of the metricses.
Use that metrics when setting up the patched font.

Windows seems to construct the font names including the PS weight.
We have some sourcefonts that are broken (i.e. have in fact different

That raises problems with the fonts on Windows.

In the post we used these information sources to determine the name and
weights/styles of the to-be-patched font:
* The filename
* The fullname (ID 4)
* The postscriptname (ID 6)
Usually it is best to use the Fullname of a font to determine its real
name and styles/weights:
The Postscript name has the advantage to have a hyphen between name and
styles/weight; but as it can not contain blanks the correct name can not
be determined by this. To get the styles/weights back we use a list of
all possible (?!) weights and styles and sort all the string parts.
This works reasonably well and the fullname is usually best.
Not so with Input Mono Condensed. Here are its names:
ID4: "InputMonoCondensed LightIta"
IF6: "InputMonoConsensed-LightItalic"
[how]
Add option to select between fullname and postscriptname as font naming
source.
For special purposes, also allow a custom (arbitrary) name input.
If that is given the specified name will be used to name the patched
font without adding any suffix - the user has full control on the name.

A lot arguments need one user supplied value, but that is not enforced.
For example
font-patcher src/unpatched-fonts/Agave/Agave-Regular.ttf --out
results in a crash, because the needed output directory has not been
passed, but the default is also not used.
The problem is that the option is defined to take any amount of values,
includeing zero values (and more than one value).
That all does not make sense. The switch does need exactly one value.
[how]
Remove the wrong nargs specification. Instead use the default, which is
'expect one value' for the default action 'store'.
Instead of a crash the user is now presented with this output:

Signed-off-by: Fini Jastrow <ulf.fini.jastrow@desy.de>
[why]
Usually the variable `logger` holds the logger object and all logging
calls got through that.
But because we use the font filename as loggername that logger object
can only be set up after the arguments have been parsed. If some
messages are to be logged before the call needs to go to the root logger
called as `logging` class.
This means one needs to take `logger` or `logging` based on the time
when someting is to be logged. That can be confusing and is easily
wrong, especially if code is shifted.
[how]
Always use the `logger` variable and just let that point to the root
logger until we set up a concrete logger.

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

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.

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]
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

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.

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
