+ * This is the interface for modesetting for drm.
+ *
+ * In order to use this interface you must include either <stdint.h> or another
+ * header defining uint32_t, int32_t and uint16_t.
+ *
+ * It aims to provide a randr 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
+ *
+ * All framebuffer, crtc and output ids start at 1 while 0 is either an invalid
+ * parameter or used to indicate that the command should disconnect from the
+ * currently bound target, as with drmModeMapOutput.
+ *
+ * Currently only one framebuffer exist and has a id of 1, which is also the
+ * default framebuffer and should allways be avaible to the client, unless
+ * it is locked/used or any other limiting state is applied on it.
