/**
* This class describes an OpenGL "surface", that is, a region of pixels
* managed via OpenGL. An OGLSurfaceData can be tagged with one of three
* different SurfaceType objects for the purpose of registering loops, etc.
* This diagram shows the hierarchy of OGL SurfaceTypes:
*
* Any
* / \
* OpenGLSurface OpenGLTexture
* |
* OpenGLSurfaceRTT
*
* OpenGLSurface
* This kind of surface can be rendered to using OpenGL APIs. It is also
* possible to copy an OpenGLSurface to another OpenGLSurface (or to itself).
* This is typically accomplished by calling MakeContextCurrent(dstSD, srcSD)
* and then calling glCopyPixels() (although there are other techniques to
* achieve the same goal).
*
* OpenGLTexture
* This kind of surface cannot be rendered to using OpenGL (in the same sense
* as in OpenGLSurface). However, it is possible to upload a region of pixels
* to an OpenGLTexture object via glTexSubImage2D(). One can also copy a
* surface of type OpenGLTexture to an OpenGLSurface by binding the texture
* to a quad and then rendering it to the destination surface (this process
* is known as "texture mapping").
*
* OpenGLSurfaceRTT
* This kind of surface can be thought of as a sort of hybrid between
* OpenGLSurface and OpenGLTexture, in that one can render to this kind of
* surface as if it were of type OpenGLSurface, but the process of copying
* this kind of surface to another is more like an OpenGLTexture. (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 OpenGL
* surface. This table helps explain the relationships between those
* "type" constants and their corresponding SurfaceType:
*
* OGL Type Corresponding SurfaceType
* -------- -------------------------
* WINDOW OpenGLSurface
* TEXTURE OpenGLTexture
* FLIP_BACKBUFFER OpenGLSurface
* FBOBJECT OpenGLSurfaceRTT
