  28  * This fairly simple test program dumps output in a similar format to the
  29  * "xrandr" tool everyone knows & loves.  It's necessarily slightly different
  30  * since the kernel separates outputs into encoder and connector structures,
  31  * each with their own unique ID.  The program also allows test testing of the
  32  * memory management and mode setting APIs by allowing the user to specify a
  33  * connector and mode to use for mode setting.  If all works as expected, a
  34  * blue background should be painted on the monitor attached to the specified
  35  * connector after the selected mode is set.
  36  *
  37  * TODO: use cairo to write the mode info on the selected output once
  38  *       the mode has been programmed, along with possible test patterns.
