[why]
When working on the font-patcher the developer needs to test the changes
on a number of fonts. This is usually a manual call of `font-patcher`
and afterwards a 'diff' of the newly created font with the 'old' font in
the patched-fonts/ directory with fontforge (which has a font-compare
option).
If you run gotta-patch-em-all normally the newly generated font will
replace the existing font and git will ALWAYS show it as different. The
reason is that at least the timestamp in the generated font has changed.
Far more easy would be if the new gotta-patch-em-all run could keep the
previous timestamps, in that way one can immediately see that the old
and new fonts are bitwise equal (via git).
Furthermore if you expect a change and want to show the differences of
old and new font in fontforge you need both fonts in the filesystem.
But a normal gotta-patch-em-all run replaces the font. A different
destination folder would help here.
[how]
Introduce two new (independent) options to
a) keep the timestamp equal to previous patch run
b) generate the fonts in a different directory
While b) is straight forward, a) is a bit more complicated, esp because
filenames can change and so on. So the script examines just one (1)
random font in the specific font directory and uses its timestamp. In
most cases this is correct enough if the developer uses gotta-patch-em-all
consequently.

[why]
All the fonts will have different timestamps, and within each font the
creation and modification date might also differ. That is quite
confusing and makes automated testing very complicated.
[how]
Use one date-time for ALL fonts and for creation and modification date
in the font file.
But do not change the date-time if we already set that somewhere before :-}
Also remove the 'special' properitary fontforge timestamp tables FFTM from
the patched fonts. This is only possible since FontForge 20th Anniversary
Edition.

[why]
The powerline glyphs (and only them) undergo a xy scaling, where both
dimensions are maximized into the 'cell'.
Normally cells are taller than wide, and everyting looks fine. But we
have square cells (e.g. 2048 * 2048) with the SymbolsOnly font, and
there might be some self patched font that has similar very-wide (in
comparison to hight) cells.
In these fonts some powerline glyphs look rather ugly. For example the
'half cicles' become very wide and un-round, the triangulars become very
pointy.
[how]
Add a new patch-set attribute 'xy-ratio'. When that is set the vertical
(y) scaling is done as usual but the horizontal (x) scaling is limited
such that the width/height ratio is maximally the attributes value.
For example setting it to 0.75 the height is maximized (as usual) but
the width is maximized to be less then 0.75 times the hight (or as wide
as the cell is, whatever is smaller).
It will work with both, 'xy' and 'pa' scaling, at least theoretically.
It has been only checked where it is used now, i.e. with 'xy'.
A possible overlap is not taken into account.
[note]
The values are taken for this reasons:
- 0.59: This is the original half-circle ratio, higher values make them
loose the (half) circular appearance
- 0.5: The half circle lines are more shallow
- 0.7: The triangulars should not be too pointy (random number)

The old doc was a bit unclear and I always had to read the code when

Signed-off-by: Fini Jastrow <ulf.fini.jastrow@desy.de>
[why]
If a ScaleGlyph is defined that ScaleRules will just be that one rule,
even if in parallel the user specified some ScaleGroups.
So it is either ScaleGroups or ScaleGlyph but not both.
If someone specifies both there is no warning or check.

Just allow both. Rewrite the ScaleGlyph to an additional (last) entry in
the ScaleGroups.

[why]
Assume a set of monospaced icons in a ScaleGroup that scatter all about
(like Braille).
With --variable-width-glyphs we forcefully remove all left side
bearings and set the width to the width of the combined bounding box.
This is not correct, usually with monospaced ScaleGroup icons we should
preserve the original advance width.
[how]
Do not remove left side bearings on ScaleGroup glyphs in
--variable-width-glyphs mode.
Set the width of any glyph in --variable-width-glyphs to the 'monoscaped
advance width' if that particular glyph has one (from a ScaleGroup).
The effect is that all positive bearings will be 'added' and put on the
right hand side of the glyph, while the glyph itself, or rather the
combined bounding box, is still strictly left aligned.

We have still a confusing naming. There are two different things that

We now have the 'old' and the 'new' GlyphsToScale things, which behave
differently, but they have the same name. That can lead to confusion. At
least I am always confused when I look at the code after a month or so.
[how]
Call the 'new' method 'ScaleGroup' instead.
The 'new' feature (which includes creating a combined bounding box and
synchronized shifting) 'ScaleGroup'.
The 'old' feature (which scales all glyphs as if they would have the
size of one reference glyph; shifting is individual) still consists of
'ScaleGlyph' and 'GlyphsToScale'.

The code looks so compliacted while in fact it is not (so much).

When only one symbol glyph is examined we conclude that it comes from a
monospaced glyph set.
This might be correct or not, but when we can not positively say it is
monospaced we should not handle it as monospaced.
[how]
We require at least TWO glyphs with the same width (and no glyph
with a different width) until we set the 'advance' bounding box
property. Which says that this particular glyph subset is monospaced.
Signed-off-by: Fini Jastrow <ulf.fini.jastrow@desy.de>
[why]
The scale-glyph-data is used only for 'pa' scales, but thereafter used
for all shifts, even if the scaling has been 'x' or 'y' or both.
As we do not use GlyphToScale for anything but 'pa' scaled glyphs that
should not make any difference right now. But it will be an obscure bug
if we ever want to handle the Powerline symbols with a scale group.
I do not know if that will ever happen, but I tried it whilst
experimenting spending hours on finding this bug.
[how]
Access the GlyphToScale data and use it even for 'x' and 'y' scaling, if
we have it for the particular glyph.
[note]
Also change 'invalid' flag from False to None.
Also use 'is None' or 'is not None' for comparisons with None.

The previous commit is somewhat incomplete in some cases and plain wrong
in others (with proportional fonts). Examples:
The Heard 0x2665 gets a positive right side bearing, which is
unexpected. The commits prevents negative right side bearings but not
positive ones.
The glyphs with overlap (which are the Powerline ones) like 0xE0B0 and
0xE0B2 end up in wrong sizes.
This can especially be seen with the Symbols-Only (non-Mono) font,
because that is (secretly) a 'Nerd Font Propo' (--variable-width-glyphs)
font.
[how]
This is kind of a design choice: As with the other patched font variants
we ignore existing borders (positive bearings) around the glyph. The
previous commit tried to keep them, which seems to be impossible and
is inconsistent). Also negative bearings would be ignored (but there are
none).
The only place where bearings come into play is now when we have
overlap. All non-overlap glyphs render without any bearing.
If we have overlap we need to
a) reduce the width by the overlap
b) introduce a negative bearing on the appropriate side
First we remove any left side bearing by transforming the glyph to the
side, such that the bearing becomes zero.
For left-side overlap we additionally transform the glyph by the overlap
amount to the left (as usual). This creates the neg. left bearing.
For right-side overlap we keep the left bearing to be zero.
After correcting the left-side bearing (by transforming) we set the
corrected width. That is the width subtracted by the overlap.
In the left-aligned case this makes the right-side bearing zero.
In the right-aligned case this results in a negative right-side bearing.
Note how fontforge handles size and bearing changes:
Fontforge handles the width change like this:
- Keep existing left_side_bearing
- Set width
- Calculate and set new right_side_bearing

Very slender symbols added to a proportional patch end up being at least
one mono-width wide, which mixes proportional and monospaces metrics.

If we use a ScaleGlyph range (i.e. use the same scaling on a range of

range.
But the data is stored nowhere.
[how]

First the new ScaleGlyph has been introduced with commit
e5768e925 font-patcher: Redesign ScaleGlyph parameter
and afterwards it has been enhanced to avoid rounding errors
with commit
983226a70 font-patcher: Fix scaleGlyph related rounding error
The later commit uses a function that explicitely says it will destroy
the glyph at a specific location, AFTER we already patched in one glyph
(namely F000).
It does not look too bad, bad that glyph is not correctly rescaled or
translated. Only that glyph is affected because only Font Awesome uses
the new ScaleGlyph capabilities, and only the first glyph of a set is
affected.
[how]
The ScaleGlyph calculations need to be done before the final glyph is
patched in. It is shifted some lines up. Usually that glyph is not
existing in the to-be-patched font, so we create a dummy first.
Also need to correct distinction between 'unicode in symbol font' and
'unicode in to-be-patched font', as this would bite us in cases where we
move the symbol's codepoint.

Normally the release zip files have a flat directory structure, i.e. all
files are in the base directory and there are no subdirs. The existing
subdirectory structure is removed on zip creation via `archive-fonts.sh`.
If the patch results have two fonts with identical name these flat
archives can not be generated. The `archive-fonts.sh` reports:
Could not create archive with the path junked (-j option) - likely
same font names for different paths, zip status: $zipStatus
Retrying with full path
But now the problem is only delayed. When the font file has the name
name the Family and SubFamily are most likely also the same for both
font files. If we install both the user (and the system) can not really
distinguish the font files anymore.
This turned up with [1] when doing a `brew style *nerd-font*` that
complains in fact about duplicate fonts to install. At that point we had
the additional problem that the subdir-path had been missing in the cask
files. So I'm not sure if it would work from a Cask standpoint (i.e.
font files are installed in subdirs).
Anyhow, this will fail when the user wants to select the font files,
because normally this is done on a Family-name basis. And identical file
name usually means identical Family-SubFamily.
Note that this ONLY happens with GohuFont, which has these subdirs:
11/complete
14/complete
uni-11/complete
uni-14/complete
The font has embedded bitmaps, but only one size. The "11" ones have
11px bitmap fonts and the "14" ones 14px bitmaps.
The "uni-" variant has much more glyphs.
Otherwise the differences are slim. From the font creation date the
"uni-" ones are newer.
[how]
Each font filename added to a cask is memorized. When the next fontfile
is to be added to the cask it is checked if we already have that
filename installed. Duplicates are then skipped.
If we have a deep archive, the fonts are added to the cask with full
relative path.
In case of Gohu that means the 11/complete variant is added (because all
files are alphabetically sorted before adding). By chance this is the
same variant that has historically been in the Cask, so no change here.
