So for example, a ScreenMode which supports screens * of 300 to 400 pixels in width, could be filtered out completely by * setting smr_MinWidth to 401. But if the smr_MinWidth is set to for * example 320 then the user is allowed to select a width of 320-400 * pixels (for this ScreenMode, and if the smr_MaxWidth allows this). * If smr_MinWidth is 200 pixels then the ScreenMode is the limiting * factor which means the user can't select ScreenModes smaller than * 300 pixels. * * The PlanarSupport and ChunkySupport tags determine which ScreenModes * are available to the user depending on their layout and number of * colors. * This structure is private and for the internal use of RtgMaster.library * and its sub-libraries ONLY.
