// This is an interface on the video renderer that provides information about
// DirectDraw with respect to its use by the renderer. For example it allows
// an application to get details of the surface and any hardware capabilities
// that are available. It also allows someone to adjust the surfaces that the
// renderer should use and furthermore even set the DirectDraw instance. We
// allow someone to set the DirectDraw instance because DirectDraw can only
// be opened once per process so it helps resolve conflicts. There is some
// duplication in this interface as the hardware/emulated/FOURCCs available
// can all be found through the IDirectDraw interface, this interface allows
// simple access to that information without calling the DirectDraw provider
// itself. The AMDDS prefix is ActiveMovie DirectDraw Switches abbreviated.

// This interface allows an application or plug in distributor to control a
// full screen renderer. The Modex renderer supports this interface. When
// connected a renderer should load the display modes it has available
// The number of modes available can be obtained through CountModes. Then
// information on each individual mode is available by calling GetModeInfo
// and IsModeAvailable. An application may enable and disable any modes
// by calling the SetEnabled flag with OATRUE or OAFALSE (not C/C++ TRUE
// and FALSE values) - the current value may be queried by IsModeEnabled
// A more generic way of setting the modes enabled that is easier to use
// when writing applications is the clip loss factor. This defines the
// amount of video that can be lost when deciding which display mode to
// use. Assuming the decoder cannot compress the video then playing an
// MPEG file (say 352x288) into a 320x200 display will lose about 25% of
// the image. The clip loss factor specifies the upper range permissible.
// To allow typical MPEG video to be played in 320x200 it defaults to 25%
