//
// (...) What we needed was a way of playing video, but have it blend into
// normal room art instead of occupying its own rectangular area. Room art
// consists of a background pic overlaid with various animating cels
// (traditional lingo: sprites). The cels each have a priority that determines
// who is on top and who is behind in the drawing order. Cels are read from
// *.v56 files (another proprietary format). A Robot is video frames with
// transparent background including priority and x,y information. Thus, it is
// like a cel, except it comes from an RBT - not a v56. Because it blends into
// our graphics engine, it looks just like a part of the room. A RBT can move
// around the screen and go behind other objects. (...)
