0025785: Visualization - introduce AIS_ColorScale presentation for Color Scale
Color scale is implemented on AIS. Draw command vcolorscale now works with AIS_ColorScale. In a qt sample VoxelDemo there was added a field AIS_ColorScale myColorsScale to control a color scale. Method displayColorScale and other methods were changed in order to work with this field.
