// This function tries to find valid device settings based upon the input device settings 
// struct and the match options.  For each device setting a match option in the 
// DXUTMatchOptions struct specifies how the function makes decisions.  For example, if 
// the caller wants a HAL device with a back buffer format of D3DFMT_A2B10G10R10 but the 
// HAL device on the system does not support D3DFMT_A2B10G10R10 however a REF device is 
// installed that does, then the function has a choice to either use REF or to change to 
// a back buffer format to compatible with the HAL device.  The match options lets the 
// caller control how these choices are made.
//
// Each match option must be one of the following types: 
//      DXUTMT_IGNORE_INPUT: Uses the closest valid value to a default 
//      DXUTMT_PRESERVE_INPUT: Uses the input without change, but may cause no valid device to be found
//      DXUTMT_CLOSEST_TO_INPUT: Uses the closest valid value to the input 
//
// If pMatchOptions is NULL then, all of the match options are assumed to be DXUTMT_IGNORE_INPUT.  
// The function returns failure if no valid device settings can be found otherwise 
// the function returns success and the valid device settings are written to pOut.
