[Declared in "../apps/compressed_io/mj2.h"]
Sets the front-to-back position of the current video track. Smaller values are further forward (closer to the viewer) than larger values. By default, all tracks have a compositing layer index of 0, with negative values used to identify tracks closer to the foreground and positive values used to identify tracks further to the background.
