For _WindowsLookAndFeel_ the `InteriorBackground` color is not been used when checkbox paint happens. In _WindowsLookAndFeel_ the CheckBox check/uncheck is drawn using `ImageCache` which is totally independent of `InteriorBackground` color in which the user expects it to be.

Lets get inputs from @prsadhuk also on this. Whether to keep checkBox.interiorBackground valid only for WindowsClassicLAF and return null for WindowsLAF Or try to find ways to return valid value for WindowsLAF.
