// CLASS DESCRIPTION (polyRawWriter)
// 
// polyRawWriter is a class derived from polyWriter.  It currently outputs in
// raw text 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)
// - other uv sets and coordinates
//
