There seems to be a documentation bug in my help file -

IDL> ?device

In the list of keywords at the top of the help window I see...

GET_DECOMPOSED (WIN, X)

If I click on the link to get to the details of the keyword I see this...

GET_DECOMPOSED

(PS, WIN, X, Z)

Regardless of the documentation confusion, it seems like a bug to me.
The language in the description of the DECOMPOSED keyword makes is seem
unambiguous that PostScript should have a decompose-able state.

Bummer.
