Lists of Open/Active Graphics Devices

Description:

     A pairlist of the names of open graphics devices is stored in
     '.Devices'. The name of the active device (see 'dev.cur') is
     stored in '.Device'.  Both are symbols and so appear in the base
     name space.

Value:

     '.Device' is a length-one character vector.

     '.Devices' is a pairlist of length-one character vectors. The
     first entry is always '"null device"', and there are as many
     entries as the maximal number of graphics devices which have been
     simultaneously active.  If a device has been removed, its entry
     will be '""' until the device number is reused.
