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.

[why]
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.

PowerlineExtra.
[how]
Just drop "Complete" from the naming.

As the name changes and thus the file name a lot of the other scripts

OriginalName Nerd Font plus Weather Mono

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

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.

Some old applications seem to depend on obsolete xAvgCharWidth values to
show two-cell glyphs correctly. Fontforge can only generate OS/2 tables
version 4, but these applications need 2 or less. In fact they seem to
not look up the version number, but rely on the value being like it

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).
Use that new property to enable/disable the box drawing glyphs.
In a way it is now also prepared to add that as command line parameter
should the need for that arise.

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
E0CA: -1230
These are the powerline glyphs which are right aligned and have overlap
and a target width of 2 cells wide.
[how]
To simplify the code add a new function that decides if a symbol shall
be one or two cells wide.
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.
[note]
I guess that the overlap correction for 'c' alignment for 2 cell wide
glyphs is also broken. But we do not have such glyphs, so we ignore it

The box drawing glyphs (center aligned) and some Powerline glyphs (that
are right aligned and have a limited xy-ratio) are positioned wrong.
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.

All the box drawing glyphs should be scaled and shifted as one (i.e.
equally). For such glyph sets we have the ScaleGroups that handle it
nicely, determining a combined bounding box and calculation scale and
shift from that bounding box instead of the actual glyph's bounding box.
But unfortunately it is hard-wired to do just 'pa' scaling. For the box
drawing glyphs we need 'xy' scaling.
[how]
The preparatory stage calculates the 'pa' factor for ScaleGroups for us.
That is mainly so because the old system worked that way and has no
notion of combinded-bounding-box. The data needed to be stored in one
number, the scale. Later came the correct shifting, which needed the
bounding box. But the scaling still relied on the one scale factor that
is used for x and y.
Instead, if we have a combinded bounding box, we ignore the
precalculated scale factor and calculate a new set of x- and y-scales
based on the requested scaling algorithm. In this way we can get 'xy' or
'pa' or even 'xy2' scaling, or whatever we like, based on the combined
bounding box.

within their design space the MDI at the new codepoints where all scaled
the same with taking the theoretical design space as ScaleGlyph.

individually scaled each Material Design Icon to fill the cell.
This lead to numerous complaints.

We take a different approach now, more conventional maybe. Especially in
the light that the older bigger icons will get dropped; and people love

When a ScaleGroup's combinded bounding box is wider than the target font
cell the actual X position of a glyph in the group depends on it's own
bonding box and not of the combinded bounding box. When doing center
or right alignment.
[how]
'Overwide' ScaleGroup glyphs are correctly placed and shifted in
position, but that would mean a negative left side bearing (i.e. glyph
extends to the left into previous 'cell').
We do not want that and it is later corrected for all glyphs. But that
is done on an individual glyph level and it is just left aligned for its
concrete bounding box (i.e. left side bearing is set to zero).
The dilemma here is that you can not really center a (combinded) glyph
within a cell, when
* the cell is smaller than the glyph
* a left bearing is not allowd
So we change the algorithm here that 'center' and 'right' alignment
mean:
* Center the glyph in the target font cell
* But if that would create a left side 'overhang' (bearing) just left
align (move it as far left as possible without creating a negative
bearing)
