[why]
The whole patching process addresses the glyphs via their unicode
number / codepoint. We ensure the adressability for the to be patched
font, but the symbol fonts can differ.
[how]
Just set the way we want to address the symbol font glyphs.

[why]
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.

[why]
For some reason we determine the bounding box xmax value of the 'normal'
extended glyphs. For the cell size we use the advance width of those
glyphs - the xmax values is not utilized at all.
But if we would ever use it, it might be good to see that something
unexpected(?) happened.
This commit is not really necessary. Maybe it is good, maybe it just
adds noise. We can always remove it later.

We had a bug that font-patcher crashes with fonts with references.

Just try such a font with all fontforge versions. Just tests if it

[why]
If a font has references in glyphs that we want to add to the essential
set of glyphs, and fontforge is old (i.e. 2020*) the patcher crashes.
[how]
The fontforge function glyph.references returns a three element tuple in
current fontforge (i.e. 20230101). But older versions skip the selection
bit and return only tuples of two.
As we use only the first tuple element we do not care about the 2nd and
possible 3rd element(s) and just thrash them.

[why]
All glyphs of the codicons set are individually maximised in size.
That leads to the curious condition that 'circle small' looks bigger
than 'cicrle' (because the line width is scaled up more -> looks bold).
Also some other 'subsets' look ugly and can not be used together.
[how]
Add appropriate ScaleGroups.
For the circles we also include one full-size circle as reference. To
get less than maximal scale for the small circles.

The Material Design Icons have for sure pairs of glyphs that people
would like to have scaled identically. Because the sheer number of
glyphs and because they are already very nicely and uniformly scaled
within their design space the MDI at the new codepoints where all scaled
the same with taking the theoretical design space as ScaleGlyph.
But that means all icons get scaled a bit smaller than before, where we
individually scaled each Material Design Icon to fill the cell.
This lead to numerous complaints.
[how]
We take a different approach now, more conventional maybe. Especially in
the light that the older bigger icons will get dropped; and people love
them.
So the uniform scaling is ditched and the individual scaling is used.

When testing 'Nerd Font' fonts (i.e. symbols may be 2 cells wide),
the output does not take that into account and does not insert
the needed blanks.
[how]
Because the actual width can not be easily determined add a
parameter (just add anything as parameter) to switch some glyphs
to two cell mode. These glyphs are in a list, i.e. hardcoded.
If the widths in non-Mono fonts is ever changed this script needs

On that OS the bash is rather old and does not have the unicode escape

embed simply the concrete characters, as done in the i_*.sh scripts.

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)
The only glyphs affected by this change are the very wide weather icons,
and here escpecially the moon phases F096 and following (target
codepoints E38E ..).

For the small and big Squares add a tiny bit of border (negative

closed squares, and that might look strange if some touch and some dont.

We have an automation for adding glyphs to the original set.
If someone throws in the svg file and adds the glyph to the icons.tsv a
new original-source font is generated.
But the added glyphs are not patched in, because that would need a
change at font-patcher (adjust the end codepoint).
This can be forgotten easily.
[how]
The maximum codepoint of our own (original + seti) set is 0xE6FF. At
0xE700 the Devicons start.
The original-source generation script now checks the offset, they may
not be negative and on the positive end we may not leave our set-range.
If that happens the script fails thus the workflow fails.
Also increate the patch range in font-patcher. If there are no icons to
patch in the symbol font the codepoints are just ignored.

There is a bit of code that is not needed anymore (or was never needed).
This makes things look more complicated than they are.

1. It is plain wrong to write that we add one (1) glyph if we do not add

both the first and the second patched in glyph).

e69a025a8 font-patcher: Fix line gap redistribution
we fixed the wrong adding instead of subtraction of the bottom gap part
from the descenders.
At least this was done for HHEA and TYPO values.
With WIN values the descenders have positive (!) numbers, so the sign
was not changed for the WIN case.
But that is wrong, as we are already in the ymin xmax coordinate system
(and took the negative of the WIN descenders). So of course here also we
need to subtract and not add.
