Enquire Extended Intuition Layer status XA

This command returns a status block about the layer status of the Imagestore

and Intuition. As the Imagestore can only control the first 14 layers of the

Intuition only the status of those layer are returned. The layer status of the

first two Imagestore layers is also included in the response for completeness.

Note that the Intuition layer status is based purely on the commands the

Imagestore has forwarded to the Intuition. This means if the Intuition is being

controlled directly either by automation or the front panel, the changes will

not be reflected in this command.
