/*
* 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 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.
*/
/*
* If we pickup an old version of drm.h which doesn't include drm_mode.h
* we should redefine defines. This is so that builds doesn't breaks with
* new libdrm on old kernels.
