+ * 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

+ *
+ * More information can be found in randrproto.txt which can be found here:

+ *
+ * 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.
