Mark,

The gif driver doesn't provide a method for the fill pattern.

The xw (and gf, png etc devices that use the xw routines) device 
provides a method for specifying the fill pattern in
$GEMPAK/source/driver/active/xw/hsfill.f
which then sets the appropriate fill bitmap pattern information
used in the fill renderer. The bitmap is rendered using the X library 
calls.

The gif driver ( based on gd from boutell.com ) does not provide a fill 
pattern renderer, and thus stubs to the generic 
$GEMPAK/source/driver/active/gn/hsfill.f.
The only valid fill for gif is a solid fill.
