Fonttools

----------------------------

- [designspaceLib] Allow to use ``\\UNC`` absolute paths on Windows (2299, 2306).
- [varLib.merger] Fixed bug where ``VarLibMergeError`` was raised with incorrect
parameters (2300).
- [feaLib] Allow substituting a glyph class with ``NULL`` to delete multiple glyphs
(2303).
- [glyf] Fixed ``NameError`` exception in ``getPhantomPoints`` (2295, 2305).
- [removeOverlaps] Retry pathops.simplify after rounding path coordinates to integers
if it fails the first time using floats, to work around a rare and hard to debug
Skia bug (2288).
- [varLib] Added support for building, reading, writing and optimizing 32-bit
``ItemVariationStore`` as used in COLRv1 table (2285).
- [otBase/otConverters] Add array readers/writers for int types (2285).
- [feaLib] Allow more than one lookahead glyph/class in contextual positioning with
"value at end" (2293, 2294).
- [COLRv1] Default varIdx should be 0xFFFFFFFF (2297, 2298).
- [pens] Make RecordingPointPen actually pass on identifiers; replace asserts with
explicit ``PenError`` exception (2284).
- [mutator] Round lsb for CF2 fonts as well (2286).

----------------------------

- [feaLib] Skip references to named lookups if the lookup block definition
is empty, similarly to makeotf. This also fixes an ``AttributeError`` while
generating ``aalt`` feature (2276, 2277).
- [subset] Fixed bug with ``--no-hinting`` implementation for Device tables (2272,
2275). The previous code was alwyas dropping Device tables if no-hinting was
requested, but some Device tables (DeltaFormat=0x8000) are also used to encode
variation indices and need to be retained.
- [otBase] Fixed bug in getting the ValueRecordSize when decompiling ``MVAR``
table with ``lazy=True`` (2273, 2274).
- [varLib/glyf/gvar] Optimized and simplified ``GlyphCoordinates`` and
``TupleVariation`` classes, use ``bytearray`` where possible, refactored
phantom-points calculations. We measured about 30% speedup in total time
of loading master ttfs, building gvar, and saving (2261, 2266).
- [subset] Fixed ``AssertionError`` while pruning unused CPAL palettes when
``0xFFFF`` is present (2257, 2259).

----------------------------

- [ttLib] Remove .Format from Coverage, ClassDef, SingleSubst, LigatureSubst,
AlternateSubst, MultipleSubst (2238).
ATTENTION: This will change your TTX dumps!
- [misc.arrayTools] move Vector to its own submodule, and rewrite as a tuple
subclass (2201).
- [docs] Added a terminology section for varLib (2209).
- [varLib] Move rounding to VariationModel, to avoid error accumulation from
multiple deltas (2214)
- [varLib] Explain merge errors in more human-friendly terms (2223, 2226)
- [otlLib] Correct some documentation (2225)
- [varLib/otlLib] Allow merging into VariationFont without first saving GPOS
PairPos2 (2229)
- [subset] Improve PairPosFormat2 subsetting (2221)
- [ttLib] TTFont.save: create file on disk as late as possible (2253)
- [cffLib] Add missing CFF2 dict operators LanguageGroup and ExpansionFactor
(2249)
ATTENTION: This will change your TTX dumps!

----------------------------

- [pens] Reverted breaking change that turned ``AbstractPen`` and ``AbstractPointPen``
into abstract base classes (2164, 2198).

----------------------------

- [feaLib] Indent anchor statements in ``asFea()`` to make them more legible and
diff-able (2193).
- [pens] Turn ``AbstractPen`` and ``AbstractPointPen`` into abstract base classes
(2164).
- [feaLib] Added support for parsing and building ``STAT`` table from AFDKO feature
files (2039).
- [instancer] Added option to update name table of generated instance using ``STAT``
table's axis values (2189).
- [bezierTools] Added functions to compute bezier point-at-time, as well as line-line,
curve-line and curve-curve intersections (2192).

----------------------------

- [COLRv1] Added ``unbuildColrV1`` to deconstruct COLRv1 otTables to raw json-able
data structure; it does the reverse of ``buildColrV1`` (2171).
- [feaLib] Allow ``sub X by NULL`` sequence to delete a glyph (2170).
- [arrayTools] Fixed ``Vector`` division (2173).
- [COLRv1] Define new ``PaintSweepGradient`` (2172).
- [otTables] Moved ``Paint.Format`` enum class outside of ``Paint`` class definition,
now named ``PaintFormat``. It was clashing with paint instance ``Format`` attribute
and thus was breaking lazy load of COLR table which relies on magic ``__getattr__``
(2175).
- [COLRv1] Replace hand-coded builder functions with otData-driven dynamic
implementation (2181).
- [COLRv1] Define additional static (non-variable) Paint formats (2181).
- [subset] Added support for subsetting COLR v1 and CPAL tables (2174, 2177).
- [fontBuilder] Allow ``setupFvar`` to optionally take ``designspaceLib.AxisDescriptor``
objects. Added new ``setupAvar`` method. Support localised names for axes and
named instances (2185).
