* @short_description: Framebuffer handling and drawing library
* @title: Framebuffer
* @include: igt.h
*
* This library contains helper functions for handling kms framebuffer objects
* using #igt_fb structures to track all the metadata. igt_create_fb() creates
* a basic framebuffer and igt_remove_fb() cleans everything up again.
*
* It also supports drawing using the cairo library and provides some simplified
* helper functions to easily draw test patterns. The main function to create a
* cairo drawing context for a framebuffer object is igt_get_cairo_ctx().
*
* Finally it also pulls in the drm fourcc headers and provides some helper
* functions to work with these pixel format codes.
