The GSET('FILTYPE',
. . . ) function selects a particular type of interior fill. If FILTYPE
is set to HATCH or PATTERN, the GSET('FILSTYLE', . . . ) function
determines the type of hatch or pattern fill used. The aspect source
flag (ASF) for FILTYPE must be set to 'INDIVIDUAL' for this attribute
to be used outside of a fill bundle.
