/// <summary>
/// Find the display mode that most closely matches the requested display mode.
/// </summary>
/// <remarks>
/// Direct3D devices require UNORM formats. This method finds the closest matching available display mode to the mode specified in pModeToMatch. Similarly ranked fields (ie. all specified, or all unspecified, etc) are resolved in the following order. ScanlineOrdering Scaling Format Resolution RefreshRate When determining the closest value for a particular field, previously matched fields are used to filter the display mode list choices, and other fields are ignored. For example, when matching Resolution, the display mode list will have already been filtered by a certain ScanlineOrdering, Scaling, and Format, while RefreshRate is ignored. This ordering doesn't define the absolute ordering for every usage scenario of FindClosestMatchingMode, because the application can choose some values initially, effectively changing the order that fields are chosen. Fields of the display mode are matched one at a time, generally in a specified order. If a field is unspecified, FindClosestMatchingMode gravitates toward the values for the desktop related to this output. If this output is not part of the desktop, then the default desktop output is used to find values. If an application uses a fully unspecified display mode, FindClosestMatchingMode will typically return a display mode that matches the desktop settings for this output. Unspecified fields are lower priority than specified fields and will be resolved later than specified fields.
