1.2.13.5.1.5.2 Frame Configuration Descriptors
The graphics module also requires its configuration through the use of Configuration descriptors. The
Graphics module can accept a frame configuration packet with or without the resizer settings. The frame
must be configured before starting the graphics port for its first frame but a new configuration descriptor is
not required unless either the frame attributes or the resizer attributes are changing from the previous
frame.
