I think I have seen the same problem when trying to make the wxWidgets=20
terminal handle fillboxes correctly. I could not make 'test' and 'load=20
"fillstyle.dem"' work correctly at the same time. I chose to make 'test'=20
not to work, i.e. give the offset as you see in your graph, but make=20
fillstyle.dem work, as the latter is the real use case. (To see it in=20
the wxWidgets terminal, you have to disable the oversampling, otherwise=20
the offset is a decimal and is negligible in the output).
