• [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 (#2769, #2773).
• [pens] Added cairoPen (#2768).
• [gvar] Read gvar more lazily by not parsing all of the glyf table (#2771).
• [ttGlyphSet] Make drawPoints(pointPen) method work for CFF fonts as well via adapter pen (#2770).
