you should decide what to do on resize. You can:
a) ignore
b)scale your shape

override JComponent#contains(int x, int y) so that it returns
polygon#contains()
or write <yourComponent>UI and override ComponentUI#contains(JComponent c,
int x, int y)

Download source of JGui 1.38 (here:
http://jgui.imagero.com/download/JGuiSrc138.zip)
and look at JShape, BasicShapeUI and ShapeUnit.
Note that this is spen source version of JGui and contains bugs (which are
fixed in full version).
