* 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:
*
* <p>Any / \ D3DSurface D3DTexture | D3DSurfaceRTT
*
* <p>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).
*
* <p>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").
*
* <p>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".)
*
* <p>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:
*
* <p>D3D Type Corresponding SurfaceType -------- ------------------------- RT_PLAIN D3DSurface
* TEXTURE D3DTexture FLIP_BACKBUFFER D3DSurface RT_TEXTURE D3DSurfaceRTT

// surface data object didn't change then the current render target
// is correct and no rendering will appear on the screen.
