/*
* 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.
