Args: glyphSet (Dict[str, Any]): A glyphset object, used to resolve components. handleOverflowingTransforms (bool): See below. If ``handleOverflowingTransforms`` is True, the components' transform values are checked that they don't overflow the limits of a F2Dot14 number: -2.0 <= v < +2.0. If any transform value exceeds these, the composite glyph is decomposed. An exception to this rule is done for values that are very close to +2.0 (both for consistency with the -2.0 case, and for the relative frequency these occur in real fonts). When almost +2.0 values occur (and all other values are within the range -2.0 <= x <= +2.0), they are clamped to the maximum positive value that can still be encoded as an F2Dot14: i.e. 1.99993896484375. If False, no check is done and all components are translated unmodified into the glyf table, followed by an inevitable ``struct.error`` once an attempt is made to compile them. If both contours and components are present in a glyph, the components are decomposed.
