that could be achieved by changing the material that is used to draw the
manipulator handles (Manipulator::setMaterial{X,Y,Z}) to one that has a
sort key that forces it to be drawn last and adding a DepthChunk to it
to disable the depth test when drawing the handles.
The tricky part then is to still be able to do picking of the handles,
though.
Hm, looking through the code, it seems that the setLength function could
in theory help here, but the length value is only evaluated during
onCreate, i.e. by the time you actually can modify the value it will
never be evaluated again :( -- at least that is the way it looks to me,
feel free to give it a try.

That is not easily possible, as one would have to dynamically resize the
handle-geometry during rendering, while being careful to actually only
resize the handle, not everything below it in the scene.
