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