/**
* This SMILType class is a special case for the 'orient' attribute on SVG's
* 'marker' element.
*
* orient = "auto | auto-start-reverse | <angle>"
*
* Unusually, this attribute doesn't have just a single corresponding DOM
* property, but rather is split into two properties: 'orientType' (of type
* DOMSVGAnimatedEnumeration) and 'orientAngle' (of type DOMSVGAnimatedAngle).
* If 'orientType.animVal' is SVG_MARKER_ORIENT_ANGLE, then
* 'orientAngle.animVal' contains the angle that is being used. The lacuna
* value is 0.
