   TODO:
-   * implement non-directbuffer support
-   * improve directbuffer draw_frame (memcpy)
+   * implement direct rendering support - NEEDS TESTING
+   * implement non-directbuffer support - NEEDS TESTING
    * check on many devices
    * implement gamma handling
-   * implement direct rendering support
 
   Thanks to Andreas Beck for his patches.
   Many thanks to Atmosfear, he hacked this driver to work with Planar
