AW: Found a good compromize now. Since the BoundRect calculation uses
getViewIndependentPrimitive2DSequence() from the ViewContact (VC), all VC
implementations of getViewIndependentPrimitive2DSequence() have to take care to
deliver eventually an extended, non-visible geometry for HitTest and/or
BoundRect calculation. To support this, i have added (renamed HitTestPrimitive)
a primitive called HiddenGeometryPrimitive2D. It decomposes to an empty
sequence, thus reneders not knowing it will be not influenced. It implements
getB2DRange() to make use of hinnde geometry to guarantee BoundRect calculation
usage. It is used in HitTest processor to check for hit with hidden geometry.

It may also be used later to get a drag polygon when not visible, but this has
to be seen.

Checking other stuff in the surroundigns, e.g. 3D behaviour...
