The AGI name is constructed from 'AGI_
wktype
_
seqno
' using the
GKS workstation type and a sequence number. The GKS workstation
type from the GKSNAMES file is used unless there is an AGITYPE
keyword for that device. A sequence number of zero is used unless
there is an explicit sequence number in the GKSNAMES file.
This routine is used by AGI and will not normally be called by an
applications program.
