/*
 * MBWMObject construction properties
 *
 * NB: the properties are only used at construction time, being passed to
 * mb_wm_object_new (); they cannot be set or queried subsequently.
 *
 * Property ids are numerical; this allows us (a) to avoid excessive use of
 * strcmp during object creation (passing 6 properties to the constructor
 * would result in each _init function doing 21 strcmp() call to retrieve it's
 * values), and (b) handle unknown properties safely.
 *
 * Property arguments can only be of the following types:
 *
 *     int,
 *     long,
 *     long long,
 *     void*,
 *
 * plus their unsigned variants.
 *
 * The property id is a 32-bit value, constructed as follows:
 *
 * Bits 31-4  : numerical id that uniquely identifies this property. Bits 31-24
 *              are reserved for private properties of any objects built out of
 *              tree to avoid clashing with default properties; with default
 *              properties bits 31-24 are always 0 (_MBWMObjectPropLastGlobal
 *              represent the highest numerical id of a default property).
 *
 * Bits 3-0   : Size of the property argument, as returned by sizeof().
 *
 * Since properties always come in id-value pairs, when an object _init()
 * function encounters a property it does not know, it needs to eat the
 * argument, the MBWMO_PROP_EAT() macro is provided for this purpose.
