// File: D3DFrame.h
//
// Desc: Class to manage the Direct3D environment objects such as buffers,
// viewports, and 3D devices.
//
// The class is initialized with the Initialize() function, after which
// the Get????() functions can be used to access the objects needed for
// rendering. If the device or display needs to be changed, the
// ChangeDevice() function can be called. If the display window is moved
// the changes need to be reported with the Move() function.
//
// After rendering a frame, the ShowFrame() function filps or blits the
// backbuffer contents to the primary. If surfaces are lost, they can be
// restored with the RestoreSurfaces() function. Finally, if normal
// Windows output is needed, the FlipToGDISurface() provides a GDI
// surface to draw on.
