Gets a property of an object.
value can be:
- an empty Value initialized by g_value_init, which will be automatically initialized with the expected type of the property (since GLib 2.60)
- a Value initialized with the expected type of the property
- a Value initialized with a type to which the expected type of the property can be transformed
In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling unset.
Note that get_property is really intended for language bindings, @get is much more convenient for C programming.
