Visualization - 2D layer viewport is updated incorrectly on resize

Description

After resizing viewer to irregular quadrangle and updating it (e.g. displaying object, highlighting object etc.) ColorScale changes it position and in case of flattened viewer exceed its bounds.

The reason is misprint in Visual3d_ViewManager::Redraw() method
      anIter.Value()->Window()->Size (aWidth, aHeight);
      aWidthMax  = Max (aWidthMax,  aWidth);
      aHeightMax = Max (aHeightMax, aWidth);

Steps to reproduce

- create colorscale
- flatten the viewer (change aspect ratio)
- create any object (e.g. box)

pload MODELING VISUALIZATION
box b 1 2 3
vinit w=1024 h=512
vsetdispmode 1
vdisplay b
vfit
vcolorscale 10 20 100 16 2 0 0
vmoveto 512 250

Note that the problem does not appear on screenshot - only during interactive execution.
