[pyup-bot]

Update fonttools[ufo,lxml] from 4.44.3 to 4.46.0.

Changelog

4.46.0

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

- [featureVars] Allow to register the same set of substitution rules to multiple features.
The ``addFeatureVariations`` function can now take a list of featureTags; similarly, the
lib key 'com.github.fonttools.varLib.featureVarsFeatureTag' can now take a
comma-separateed string of feature tags (e.g. "salt,ss01") instead of a single tag (3360).
- [featureVars] Don't overwrite GSUB FeatureVariations, but append new records to it
for features which are not already there. But raise ``VarLibError`` if the feature tag
already has feature variations associated with it (3363).
- [varLib] Added ``addGSUBFeatureVariations`` function to add GSUB Feature Variations
to an existing variable font from rules defined in a DesignSpace document (3362).
- [varLib.interpolatable] Various bugfixes and rendering improvements. In particular,
a new test for "underweight" glyphs. The new test reports quite a few false-positives
though. Please send feedback.

4.45.1

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

- [varLib.interpolatable] Various bugfixes and improvements, better reporting, reduced
false positives.
- [ttGlyphSet] Added option to not recalculate glyf bounds (3348).

4.45.0

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

- [varLib.interpolatable] Vastly improved algorithms. Also available now is ``--pdf``
and ``--html`` options to generate a PDF or HTML report of the interpolation issues.
The PDF/HTML report showcases the problematic masters, the interpolated broken
glyph, as well as the proposed fixed version.
