| * In order to use this interface you must include either <stdint.h> or another |

| * |
| * It aims to provide a randr1.2 compatible interface for modesettings in the |
| * kernel, the interface is also ment to be used by libraries like EGL. |
| * |
| * More information can be found in randrproto.txt which can be found here: |
| * http://gitweb.freedesktop.org/?p=xorg/proto/randrproto.git |
| * |
| * There are some major diffrences to be noted. Unlike the randr1.2 proto you |
| * need to create the memory object of the framebuffer yourself with the ttm |
| * buffer object interface. This object needs to be pinned. |
