[vtkusers] Resizing vtkSliderRepresentation2D

The issue is that the widget maintains its absolute size when the window is
resized. It sizes up correctly when
a mouse interaction happens within the rendered area. So what my hack is
doing is mimicking a middle button
press which indirectly resizes the widgets correctly.

It is not clear what changing the Point1Coordinate and a Point2Coordinate in
normalized coordinates would do. As
I want to maintain the same normalized locations when the window resizes.
