In OpenGL 1.1 ES ...
1) Is it possible to directly copy from one texture into another texture?
2) Is it possible to copy directly from one buffer into another?
3) Are there FRONT_RIGHT, FRONT_LEFT, BACK_RIGHT, and BACK_LEFT buffers or just FRONT and BACK buffers?
4) Can a texture be assigned as a buffer or a buffer as a texture? (This would do the same as 1 and 2 above)
I am specifically working with iOS devices.
