Overrides this method to ensure that the new background non-selection color is not
a {@link GColorUIResource}. Some Look and Feels will ignore color values that extend
{@link UIResource}, choosing instead their own custom painting behavior. By not using a 
UIResource, we prevent the Look and Feel from overriding this renderer's color value.

@param newColor the new background non-selection color
