/**
 * This class describes a D3D "surface", that is, a region of pixels
 * managed via D3D.  An D3DSurfaceData can be tagged with one of three
 * different SurfaceType objects for the purpose of registering loops, etc.
 * This diagram shows the hierarchy of D3D SurfaceTypes:
 *
 *                               Any
 *                             /     \
 *                    D3DSurface     D3DTexture
 *                         |
 *                   D3DSurfaceRTT
 *
 * D3DSurface
 * This kind of surface can be rendered to using D3D APIs.  It is also
 * possible to copy a D3DSurface to another D3DSurface (or to itself).
 *
 * D3DTexture
 * This kind of surface cannot be rendered to using D3D (in the same sense
 * as in D3DSurface).  However, it is possible to upload a region of pixels
 * to a D3DTexture object via Lock/UnlockRect().  One can also copy a
 * surface of type D3DTexture to a D3DSurface by binding the texture
 * to a quad and then rendering it to the destination surface (this process
 * is known as "texture mapping").
 *
 * D3DSurfaceRTT
 * This kind of surface can be thought of as a sort of hybrid between
 * D3DSurface and D3DTexture, in that one can render to this kind of
 * surface as if it were of type D3DSurface, but the process of copying
 * this kind of surface to another is more like a D3DTexture.  (Note that
 * "RTT" stands for "render-to-texture".)
 *
 * In addition to these SurfaceType variants, we have also defined some
 * constants that describe in more detail the type of underlying D3D
 * surface.  This table helps explain the relationships between those
 * "type" constants and their corresponding SurfaceType:
 *
 * D3D Type          Corresponding SurfaceType
 * --------          -------------------------
 * RT_PLAIN          D3DSurface
 * TEXTURE           D3DTexture
 * FLIP_BACKBUFFER   D3DSurface
 * RT_TEXTURE        D3DSurfaceRTT
