Detailed Description

HasWedgeTexCoords concept is satisfied only if a Element class provides the types and member functions specified in this concept. These types and member functions allow to access to an vcl::comp::WedgeTexCoords component of a given element.

Note that this concept does not discriminate between the Horizontal WedgeTexCoords component and the vertical OptionalWedgeTexCoords component, therefore it does not guarantee that a template Element type that satisfies this concept provides WedgeTexCoords component at runtime (it is guaranteed only that the proper member functions are available at compile time).
