My experience is that there continue to be bugs in filled contours,
particularly when there are missing data, and when the contours "bleed"
off the plot. Some contours dont get filled in, and others overrun
adjacent areas (?).

3.6.1a is suppose to have some fixes to these problems, and here is
something from rel_dotes.doc:

6/29/94
Added a new keyword, CELL_FILL, to CONTOUR that fills
each cell on an individual basis. This method avoids
many of the problems with /FILL in which contours that
hit missing data cells or edges of maps are not filled.
The disadvantage of this method is that many small
polygons are produced. Also fixed some bugs with /FILL
that caused incorrectly colored areas.


My Note: you have to add /cell_fill, not replace /fill.

I just did a quick test of this, and things seem to be better, but
not all the way fixed (I think). I dont see any more overruning
adjacent areas, but I've still got non filled areas. This is just a
quick look, and I will look at it closer.
Note I use map_set, /cylindrical to establish my coord. system. I suspect
that contouring does better in other coord systems.
