1957	// Description:
1958	//
1959	// Takes a pointer to a partially or fully filled in pThisDisplay and a pointer
1960	// to an empty DDHALINFO and fills in the DDHALINFO. This eases porting to NT
1961	// and means that caps changes are done in only one place. The pThisDisplay
1962	// may not be fully constructed here, so you should only:
1963	// a) Query the registry
1964	// b) DISPDBG
1965	// If you need to add anything to pThisDisplay for NT, you should fill it in
1966	// during the DrvGetDirectDraw call.
1967	//
1968	// The problem here is when the code is run on NT. If there was any other way...
1969	//
1970	// The following caps have been found to cause NT to bail....
1971	// DDCAPS_GDI, DDFXCAPS_BLTMIRRORUPDOWN, DDFXCAPS_BLTMIRRORLEFTRIGHT
