+/**
+* 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
