Enlarge radius of box drawings arcs
Before, the diagonal parts were the same as in the capital O. But that

recent change to add JOIN_R in order to join up properly.

Add JOIN_R and JOIN_D flags, and extend effects of JOIN_*
The new flags mark glyphs that join to the right and downwards. The
effect of these, and a new effect of JOIN_U and JOIN_L, is to arrange
that getpix() treats pixels beyond the edge of the character cell as
repeating the last row of real pixels.
In practice, this means that a diagonal stroke touching the right or
bottom edge of the cell will now be drawn as though it turns into an
orthogonal stroke across the edge rather than as though it stops. This
doesn't affect the outline of any existing glyph.
There is a more subtle consequence, which is that joining glyphs no
longer get edge hints on their joining edges. I think that's an
improvement: such hints might move those edges so that they don't touch
the adjacent character, which would be rather unhelpful.

Microsoft Windows where the version of 'v' before this patch ended up
horribly distorted when rendered at 20 ppem in Bedstead Condensed. To
try to avoid such horrors, we now select hints starting at the outside
edges of the character and working inwards, instead of going from left
to right or top to bottom. This means that where hints conflict,
we'll tend to choose the ones towards the outside edge of the

Don't emit counter hints for horizontal stems
Microsoft Windows 11 pays some attention to counter hints, and the
results are disastrous. Specifically, at awkward ppem, characters
with counter hints end up one pixel smaller that characters without
them. That makes the counters the same size, and puts every
horizontal stem squarely on a pixel, but means that cap height is all
wobbly, which looks horrible. Additionally, some characters ('2' and
'3', at least) end up grossly distorted, with the top of the character
either stretched way above the character cell or squashed down to the
centre line.
Turning off the counter hints solves these problems. Windows does
then draw the 'B' with its centre-line below the centre rather than
above it, but that's not a regression from 002.009. As far as I can
tell, FreeType 2.12.1 ignores counter hints entirely. At least, the
output of ftlint at 11 ppem is the same before and after this change.
Vertical counter hints survive. They're also ignored by FreeType
2.12.1 (as are all vertical stem hints), but they seem to have a
broadly positive effect in Windows.

Further SOURCE_DATE_EPOCH simplification
Rather than mucking about with errno, we can just take advantage of the
fact that on overflow, strtoull() is specified to return ULLONG_MAX,
which is guaranteed to be (much) bigger than the maximum
SOURCE_DATE_EPOCH that we can cope with. So our usual range check can
cope with overflow as well.

Handle SOURCE_DATE_EPOCH in unsigned long long, not unitmax_t
unsigned long long is guaranteed to be big enough. No need to go
bigger.

Slightly simplify SOURCE_DATE_EPOCH handling
Subtracting 30 years' worth of seconds from the date and then adding
2000 years is unnecessary when we can just add 1970 years instead.

Add a "Unique font identifier" string (name ID 3)
This seems to be necessary for the font viewer in MS Windows 11 to
consider the font to be valid. The semantics of this field are not
documented in the OpenType spec, but the Apple TrueType spec does at
least give an example. I've roughly followed Apple's example, putting
together the full name, version number, and build date that we already
have to hand and include in the font. Between them those should
uniquely identify reasonable builds of Bedstead fonts without adding
extra complexity or non-reproducibility.

Policy on Git commit messages in CONTRIBUTING
I've never been comfortable with constructing or editing commit
messages that will appear under someone else's name, but on the other
hand I don't want to be forced either to use someone else's message
untouched or to remove their name from the "Author" field. Allowing
myself to make clearly-marked edits seems to be a good compromise, and
square brackets are a common way of marking edits and editorial
comments.

More portable handling of SOURCE_DATE_EPOCH
Now we don't make any assumption about being on a POSIX system, and
instead have our own implementation of gmtime(). This turns out to be
shorter than the comment explaining why the previous code was more or
less valid.
While I'm in the area, also fail if the year is after 9999, since
asctime() causes undefined behaviour in those cases.

Add E with cedilla
That's a real cedilla, and hence gets the SAA5054 angular form. It's
also the last Latin letter with a cedilla that isn't blocked by
something else. At least, until Unicode adds a new one.

Glyphs for G, K, L, N, and R with comma below
These are the remaining characters that Unicode calls "WITH CEDILLA" but
that the standard (and code charts) say should actually have a comma
below by default.

Redesign Hcedilla and hcedilla
The Unicode code charts and all the fonts I have conveniently to hand
are agreed that the cedilla should be attached to the letter, usually
to the left leg. So now it is in Bedstead as well. This also allows
the body of the letter to return to its normal shape.
