The PointToSegmentPen translates between PointPen and (Segment)Pen
protocol.
In the SegmentPen protocol, closed contours always imply a final 'lineTo'
segment from the last oncurve point to the starting point.
So the PointToSegmentPen omits the final 'lineTo' segment for closed
contours -- unless the option 'outputImpliedClosingLine' is True
(it is False by default, and defcon.Glyph.draw method initializes the
converter pen without this option).
However, if the last oncurve point is on a "line" segment and has same
coordinates as the starting point of a closed contour, the converter pen must
always output the closing 'lineTo' explicitly (regardless of the value of the
'outputImpliedClosingLine' option) in order to disambiguate this case from
the implied closing 'lineTo'.
If it doesn't do that, a duplicate 'line' point at the end of a closed
contour gets lost in the conversion.

I forgot to do this before releasing 4.0.0 -- but it's ok.
Even if wheel file name incorrectly says 'py2.py3', PyPI reads the metadata
from the package and returns the correct version of fonttools (3.44.0 vs 4.0)
depending on the version of the python interpreter used to run pip installer.
the boilerplate .gitignore from Github was too broad and all-catching.
It included things like 'lib' (which is where all modules are in fonttools...)
or stuff for tools which we never use.
So I just deleted those.
Similar to what we do with “post” table names. I’d have said the font is
broken, but all applications I tried it with loaded it just fine, though
they differed in which glyph to pick from the duplicate ones.

After subsetting some strikes might be empty (strikes don’t have to
cover all glyphs equally) which would cause a key error later when
saving the table.

[ttLib] Allow the glyf table to be incomplete (to not contain everything from the glyph order) when writing to XML. This partially addresses #684 in that it will allow the font Ambrosia.otb to be dumped with ttx (but not recompiled). Log a warning when a glyph is not present.
