If the value is `None`, the default coordinate as per 'fvar' table for
            that axis is used.
            The limit values can also be (min, max) tuples for restricting an
            axis's variation range. The default axis value must be included in
            the new range.
        inplace (bool): whether to modify input TTFont object in-place instead of
            returning a distinct object.
        optimize (bool): if False, do not perform IUP-delta optimization on the
            remaining 'gvar' table's deltas. Possibly faster, and might work around
            rendering issues in some buggy environments, at the cost of a slightly
            larger file size.
        overlap (OverlapMode): variable fonts usually contain overlapping contours, and
            some font rendering engines on Apple platforms require that the
            `OVERLAP_SIMPLE` and `OVERLAP_COMPOUND` flags in the 'glyf' table be set to
            force rendering using a non-zero fill rule. Thus we always set these flags
            on all glyphs to maximise cross-compatibility of the generated instance.
            You can disable this by passing OverlapMode.KEEP_AND_DONT_SET_FLAGS.
            If you want to remove the overlaps altogether and merge overlapping
            contours and components, you can pass OverlapMode.REMOVE. Note that this
            requires the skia-pathops package (available to pip install).
            The overlap parameter only has effect when generating full static instances.
        updateFontNames (bool): if True, update the instantiated font's name table using
            the Axis Value Tables from the STAT table. The name table will be updated so
            it conforms to the R/I/B/BI model. If the STAT table is missing or
            an Axis Value table is missing for a given axis coordinate, a ValueError will
            be raised.
