+ *
+ * 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

+ * buffer object interface. This object needs to be pinned.
