// CLASS DESCRIPTION (polyX3DWriter)
// 
// polyX3DWriter is a class derived from polyWriter.  It currently outputs, in
// X3D compliant format, the following polygonal mesh data:
// - faces and their vertex components
// - vertex coordinates
// - colors per vertex
// - normals per vertex
// - current uv set and coordinates
// - component sets
// - file textures (for the current uv set)
//
