Changes the background color that is used when adding samples to a video track.

Parameter movieRef is the reference to the movie instance. The movie reference must have been previously obtained with a call to QM_NewMovieFromFile.

Parameter trackID is the ID of the track.

Parameter backColor is the background RGB color. It must be expressed as a longint, using 4Dv6's RGB color notation format (0x00RRGGBB - see the SET RGB COLOR 4D command). 4D's RGB color constants can also be used.

QMedia sets the default background color to white (0x00FFFFFF).
