Evaluating Control Link Expressions

* Get the Vertices' Texture Coordinate components

* Texture Coordinates can not be inherited (so don't process inheritance),

* but Texture Coordinates can appear in Hierarchical Tables (so *do*

* directly attach table components), and Texture Coordinates can have

* Control Links (so *do* evaluate static Control Links).
