// shadowEnable - enables shadows on the object.
// shadowCanMove - performance tweak that skips surface recalc when object is not moveable.
// shadowCanAnimate - performance tweak that skips image recalc when object is not animated.
// shadowSelfShadow - enables self-shadowing.
// shadowDTSShadow - enables casting onto other DTS objects (requires self-shadowing, currently limited to other ShapeBase derived objects, ***see Note 1***)
// shadowSize - shadow texture size (must be a power of two).
// shadowAnimationFrameSkip - performance tweak that skips image recalc for X rendered frames (ignored when self-shadowing).
// shadowMaxVisibleDistance - maximum distance from the viewer the shadow is visible.
// shadowProjectionDistance - distance the shadow projects from the casting object.
// shadowSphereAdjust - expands the shadow image out beyond the object bounding box by X times (for objects with bad bounding boxes).
// shadowBias - adjusts the shadow's error correction.
