In Excel hidden drawing objects aren't printed. When not
hidden, printing is controlled by a separate 'Print object'
setting.

Only rely visibility setting for now, but properly:
visible means also printed, hidden means not printed.
Ie. import visible property also as printable, and only
output visible property in XLS(X) formats.

For the future, in XLSX format printability is controlled by
attribute 'fPrintsWithSheet' of element 'clientData', don't
know about XLS, there fUsefPrint/fPrint bits don't appear to
be used anymore (see note in tdf#119639).
