/*=*******************************************
A display is a coordinated set of video/audio outputs that are usually sent
to one TV set.
Each display may have multiple outputs (e.g. svideo, composite), but each
output will carry the same content.

Decode windows are boxes of video content on a display. You control decode
windows and audio volume through the display API.

Some chips support more than one display (7038, 7320 and Venom2).
For these systems, you will open two bdisplay_t handles and have one bdecode_window_t handle
created for each display.
