- Update to 4.37.1
* [subset] Fixed regression introduced with v4.37.0 while subsetting
the VarStore of HVAR and VVAR tables, whereby an
AttributeError: subset_varidxes was thrown because an apparently
unused import statement (with the side-effect of dynamically binding
that subset_varidxes method to the VarStore class) had been
accidentally deleted in an unrelated PR
* [pens] Added cairoPen
* [gvar] Read gvar more lazily by not parsing all of the glyf table
* [ttGlyphSet] Make drawPoints(pointPen) method work for CFF fonts
as well via adapter pen
* [cff.specializer] Fixed issue in charstring generalizer with the
blend operator
* [varLib.models] Added support for extrapolation
* [ttGlyphSet] Ensure the newly added _TTVarGlyphSet inherits from
_TTGlyphSet to keep backward compatibility with existing API
* [kern] Allow compiling legacy kern tables with more than 64k entries
* [visitor] Added new visitor API to traverse tree of objects and
dispatch based on the attribute type: cf. fontTools.misc.visitor
and fontTools.ttLib.ttVisitor. Added fontTools.ttLib.scaleUpem
module that uses the latter to change a font's units-per-em and
scale all the related fields accordingly
