Somehow the `IBM 3270 SemiCondensed` font turn out as
`IBM3270Semi Nerd Font Condensed`.
The 3270 font always had the quirk to have a non-standard style with a
dash. We have specific code to circumvent that.
[how]
After updating 3270 the 'Narrow' had been renamed to 'Condensed' and so
our specific patch did not work anymore.
Adapt the regex to find the new style that needs correction.

Scaling the glyphs individually breaks a lot of glyph pairs or groups,
for example F0718-F071E.
[how]
Use one ScaleGlyph for the complete set. The set itself is already very
well scaled, i.e. all glyphs are maximized in a given design space and
that they look good next to pairing glyphs.
There is no need to use ScaleRules which is quite costly for such a big
range of glyphs (they all are copied twice in the process).

ScaleGlyph always did scaling only (no translation) based on one

ScaleGroups does scaling and translation but can not work with one
reference glyph but constructs always a combined bounding box.
Missing is a way to scale AND translate, but with only one reference
glyph.

Invent GlyphsToScale+ keyword, that supports just that.

The vertical overlap is still not 'pixel perfect', it is off by a small
amount that differs by font.
[how]
The reason is the wrong formula. We take the relative widths of the
glyph to calculate the factor needed to add an overlap in height.
Of course we need to take the relative heights *duh*.
Sometimes I think how dumb can a single person be? :-}
I would say this is copy-and-paste laziness.

[why]
The change introduced with commit
Default some Powerline glyphs to '2 cells wide'
scales some Powerline glyphs to fit exactly into a 2 cell width. That
looks good on 'normal' fonts, but when the font becomes wider and less
tall at some point that is just too wide.
This is especially the case with the SymbolsOnly font which has a 1:1
aspect ratio. Two cell Powerline glyphs would have an aspect ratio of
2:1 which is unusable.
[how]
Check the destination font cell aspect ratio.
When a two-cell glyph would be wider than 1.6 times its height the
two-cell-mode is forbitten and all Powerline glyphs are scaled into one
cell width.

[why]
The vertical overlap has never been a problem (as far as I know). It is
maybe good to have some overlap for the terminal emulators that support
vertical overlap.
On terminals that truncate at the nominal cell border too much overlap
looks bad, i.e. the glyphs 'distorted'.
If we ever increase the overlap it is most likely be meant to be the
left-right overlap.
Note that the glyphs are usually valign='c' and the overlap is
distributed half top and half bottom. There are no other valign values
implemented (just 'not align' which is ... most likely bad).

[why]
We have two variables that hold the same data (sym_dim and dim), which
is confusing ('why do we have it?').
There is also the big 'if' on 'do we want to scale', which contains too
much. In the unlikely event that we have a glyph that needs to be scaled
by 1.0 AND have an overlap the code produces the wrong results.

When we scale all Powerline glyphs also horizontally (in X direction) to
'one cell' some might look a bit too small; especially because they were
very big previoulsy (before commit 'font-patcher: Do x-scale powerline
glyphs').
[how]
To get them to a reasonable and always equal width a new scale code is
introduced: '2'. It is evaluated in 'x' or 'y' scaling contexts and
doubles the target cell width (unless a "Nerd Font Mono" is generated
where all glyphs must be one cell wide).
Signed-off-by: Fini Jastrow <ulf.fini.jastrow@desy.de>
[why]
Most Powerline glyphs have a little bit over overlap to the previous or
next glyph to prevent a 'break' in a colored prompt.
It does not make sense to have overlap with glyphs that can never
produce any of that issues, i.e. glyphs that are not filled to the
border. Like all the line-ish glyphs.
Signed-off-by: Fini Jastrow <ulf.fini.jastrow@desy.de>
[why]
For the non-Mono variants ('Nerd Font' and 'Nerd Font Propo') the
Powerline symbols are scaled in Y but the width is just kept from the
symbol font, whatever that might be (and if it makes any sense).
If you have for example the triangular thing (`E0B0`) it is bigger than
'one cell' and extrudes into the following cell (on 'Nerd Font'). For
the other side (`E0B2`) it is even worse; it is right aligned in the
current cell and so (because it is wider than one cell) it protrudes
into the previous cell.
[how]
Just allow not only Y scaling but also X scaling for non-Mono fonts.
[note]
This is of relevance just for 'xy' scaling, and only the Powerline
symbols do that.

[why]
The overlap formula seems to be off sometimes. Although the shift is
correct (and thus the number of 'pixels' that overlap), but the non
overlapping part of the glyph is often not as wide as expected, off by
up to some percent.
[how]
The formula is too simple. It just calculates an additional scale factor
on top of the already existing factor. To get it 'pixel perfect' we need
to calculate first how much the glyph fills the cell - because we want
the overlap to be in 'cell percent' and not 'glyph percent'. That might
be sometimes the same (if the cell is filled completely), but usually it
is not completely full, and that means the overlap will be smaller than
intended.
[note]
To get the current glyph bounding box we pull some lines up in the code
that get the 'dim' variable.
Also use float constants to calculate with float variables.

[why]
On very small source fonts the patched-in symbol-glyphs can become very
big and create overlay problems. It might be desirable to scale them
down to 'two advance widths'.
[how]
It could be that the glyphs in question are in a ScaleGlyph range. So we
need to activate that code also for non-single fonts.
Further we allow two slots wide symbols in get_scale_factors() for those
fonts.
Now we take the computed scale factors for non-single fonts - only if we
scale down and not up. It will confuse/upset people if the known symbols
in their fonts suddenly become bigger - and it also does not look right.

[why]
The glyph rescaling is scattered about two functions and several
branches. It becomes hard to follow what is done when and why.
[how]
Use one function that determines any glyph scaling, that includes all
handling except ScaleGlyph related stuff.
This simplifies the code in copy_glyphs() a lot, and keeps all the scaling
in get_scale_factors().
[note]
No behavioral change introduced with this.
[note]
Well, it fixes the possible problem (it will never happen, but lurks)
that a glyph is in the ScaleGlyph range AND has Y scaling set.
The old code first uses the ScaleGlyph scaling and afterwards violates
it by mindlessly doing the Y stretch. This would not happen anymore with
the new code. If a ScaleGlyph is specified for a certain glyph, that
ScaleGlyph is followed and nothing else.

[why]
The 'monospace' width is determined by examining all the 'normal' glyphs
and taking the widest one.
'Normal' means 0x00-0x17f: the Latin Extended-A range.
Unfortunately some fonts that claim to be monospaced still have some
glyphs that are wider than the others.
[how]
Exclude a small group of glyphs from the 'find the widest glyph'.
The list is specifically targetted at the fonts we patch, see PR #1045.
Most of these glyphs are either visually small and it is unclear why
they are too wide (like double-quotes), or they are from the real
extended set, notably all the Eth (D with a slash) and other added-slash
or added-caron glyphs.
In ignoring them we might 'break' these specific glyphs for the people
who use them (like: they extend out of the cell into the next), but that
is the only way to keep the 'monospaced promise' without redesigning the
actual font.
But without these exceptions we have Nerd Font Mono fonts that increase
the cell width so that 'normal text' is rendered almost unreadable.
So this is an improvement for most users; and I see no way so solve
these font issues for all users (without redesigning the font itself ;).
Also add a 'warning' if a (still) problematic font is to be patched.
As reminder for self-patcher or when we add fonts here.
