   2. Uses local coordinates and has preferred size
   3. Overrides translate[To/From]Parent(Translatable t) methods so they take preferred size, divide this by current size and use these scale factors to translate t.

   should be used only for a couple of prominent attributes to avoid
   overloading the diagram

   this is not very nice since items are ordered alphabetically rather than
   by meaning

   this would be only useful if the (contents of the) tab could be switched
   depending on the current selection including the case that the whole tab
   is hidden if not appropriate
   Is this possible?

<extension point="org.eclipse.wst.common.ui.properties.propertySections">
<propertySections ...>
<propertySection
tab = "MyCircuitTab"
filter =
"org.eclipse.gmf.runtime.diagram.ui.properties.filters.GenericModelElementFi
lter"
...>
<input type
="org.eclipse.gmf.examples.runtime.diagram.logic.model.Circuit"/>
</propertySection>
<propertySections>
