// Description: This Interface was designed for the purpose of exposing the TIFFClippingPath
// code from the Image plugin. Photoshop images have a series of '8BIM' records/resources
// stored in different places depending on the image type. Once located and decoded using
// ConvertPSResourcesToPMTags(), the result can be passed to the TIFFClippingPath implementation
// to create a polygon.
