/**
* 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
