 AttrMakeFlatTransp ()
virtual AttrFillGeometry * MutateFill (AttrFillGeometry *FillToMutate)
 Forces a 50% flat transparency.
virtual NodeAttribute * GetOtherAttrToApply (BOOL *IsMutate)
 Some attributes require a secondary atribute to be changed when they are changed. This routine obtains a pointer to the secondary attribute to apply.

Detailed Description
