/**
 * \defgroup Command2Property Command to property bridge
 *
 * It is used to handle most commands that just set a property
 * and optionally display something on the OSD.
 * Two kinds of commands are handled: adjust or toggle.
 *
 * Adjust commands take 1 or 2 parameters: <value> <abs>
 * If <abs> is non-zero the property is set to the given value
 * otherwise it is adjusted.
 *
 * Toggle commands take 0 or 1 parameters. With no parameter
 * or a value less than the property minimum it just steps the
 * property to its next or previous value respectively.
 * Otherwise it sets it to the given value.
