... done.
A very big "thank you" to Larry for supporting me in this. :-)
- From the point of view of the Print/Layout plug-in this makes it
a lot easier to produce hi quality output without tampering
with the size of the LayerViewPanel or other ugly workarounds.
Of cause on the callers side you cannot assume that the
set() call is already there [1]. Even if SkyJUMP and OpenJUMP
features it we have a bunch of other derivates.
It would be very nice to have it at least in deeJUMP or PirolJUMP
as well.
Ugo, Michael (Brüning), any comments about this topic?

[1] java.lang.reflect is our friend here to check if it exists
and call it if it's possible.
