To document the implementation on a FlightGear aircraft from the aircraft developer's point of view, I've chosen one of my pet projects, the Eurofighter EF2000 V2.0 which will be released in early 2015.

The intention is to use Canvas to allow multiple textures per livery, in this case those textures being the original livery paintwork and another, alpha-transparent texture consisting of dirt steaks specifically added to the livery paintwork to match with vents, seams and other sources of grimy build-ups. The intention is to allow dynamic management of the transparency of the dirt layer according to time and exposure to various elements, maintaining compatibility with the standard livery switching method and working similarly whether Rembrandt is enabled or not.
