79 * This class describes a D3D "surface", that is, a region of pixels
80 * managed via D3D. An D3DSurfaceData can be tagged with one of three
81 * different SurfaceType objects for the purpose of registering loops, etc.
82 * This diagram shows the hierarchy of D3D SurfaceTypes:
83 *
84 * Any
85 * / \
86 * D3DSurface D3DTexture
87 * |
88 * D3DSurfaceRTT
89 *
90 * D3DSurface
91 * This kind of surface can be rendered to using D3D APIs. It is also
92 * possible to copy a D3DSurface to another D3DSurface (or to itself).
93 *
94 * D3DTexture
95 * This kind of surface cannot be rendered to using D3D (in the same sense
96 * as in D3DSurface). However, it is possible to upload a region of pixels
97 * to a D3DTexture object via Lock/UnlockRect(). One can also copy a
98 * surface of type D3DTexture to a D3DSurface by binding the texture
99 * to a quad and then rendering it to the destination surface (this process
100 * is known as "texture mapping").
101 *
102 * D3DSurfaceRTT
103 * This kind of surface can be thought of as a sort of hybrid between
104 * D3DSurface and D3DTexture, in that one can render to this kind of
105 * surface as if it were of type D3DSurface, but the process of copying
106 * this kind of surface to another is more like a D3DTexture. (Note that
107 * "RTT" stands for "render-to-texture".)
108 *
109 * In addition to these SurfaceType variants, we have also defined some
110 * constants that describe in more detail the type of underlying D3D
111 * surface. This table helps explain the relationships between those
112 * "type" constants and their corresponding SurfaceType:
113 *
114 * D3D Type Corresponding SurfaceType
115 * -------- -------------------------
116 * RT_PLAIN D3DSurface
117 * TEXTURE D3DTexture
118 * FLIP_BACKBUFFER D3DSurface
119 * RT_TEXTURE D3DSurfaceRTT
