The fill looks much better.  I did find two minor issues.

The file format indentation is incorrect.  The hatch tokens should be
indented two spaces from the "fill" token.  In other words, remove the
space from the beginning of the output string and set the indent level
to aNestLevel+2.

The "Smooth value" edit control in the zone properties dialog does not
allow me to enter non-integer values on linux (I didn't test it on
windows) and the spinner controls are not incrementing or decrementing
by 0.1 or at least it's not being displayed correctly.  Once those two
issues are resolved, I think its ready to merge unless there any other
objections.

Cheers,

Wayne
