20 * All objects (coord and shapes) should have mb_obj_t as first member
21 * variable. obj_type is used to identify type of an object. Please,
22 * use MBO_TYPE() to return this value. MBO_TYPE() will type-casting the
23 * object to mb_obj_t and return obj_type. MBO_TYPE() is a left-side
24 * value.
