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