Configurator API

ID2DXConfigurator is a pseudo-COM interface that can be used to integrate with D2DX. It is suitable e.g. for "high-res" mods that want to use arbitrary resolutions.

It can be accessed via the helper d2dx::TryGetConfigurator, or manually by using LoadLibrary/GetProcAddress to get a pointer to _D2DXGetConfigurator@4.

Note that the object is not really refcounted and there's no need to call AddRef/Release.

Note also that the built-in resolution mod in D2DX will be disabled if D2DXGetConfigurator is called prior to the first Glide call made.

Example use:

		ID2DXConfigurator* d2dxConfigurator = d2dx::TryGetConfigurator();
		if (d2dxConfigurator)
		{
			d2dxConfigurator->SetCustomResolution(1000, 500);
		}	
		grSstWinOpen(hWnd, ...)
