Description Alex Szpakowski 2016-03-10 02:31:49 UTC 
The function SDL_GL_BindTexture...

* Only makes sense when the renderer has an OpenGL or OpenGL ES backend, which is only the case some of the time.
* Overwrites the current OpenGL context binding with the renderer's internal context.
* Binds an unspecified amount and type of OpenGL textures to unspecified texture units. In practice, it uses texture units 0 - 2 and either GL_TEXTURE_2D or GL_TEXTURE_RECTANGLE, depending on some implementation-dependent factors.

These points, especially the last one, make it useless for practical purposes - you can't rely on it doing anything that you can use, and in order to use it you have to know details about the renderer's code which may change in any version. I think the functions should be removed.

For review in SDL 2.1.

Maybe we just need to define what it's doing more completely?
