ed) are kept in the store, and their deltas multiplied
    by the scalar support of the axes to be pinned at the desired location.

    Args:
        variations: List[TupleVariation] from either 'gvar' or 'cvar'.
        axisLimits: Dict[str, Union[float, NormalizedAxisRange]]: axes' coordinates for
            the full or partial instance, or ranges for restricting an axis' min/max.
        origCoords: GlyphCoordinates: default instance's coordinates for computing 'gvar'
            inferred points (cf. table__g_l_y_f._getCoordinatesAndControls).
        endPts: List[int]: indices of contour end points, for inferring 'gvar' deltas.

    Returns:
        List[float]: the overall delta adjustment after applicable deltas were summed.
