This means that all functions which were returning or taking as parameter an image id (as gint32) are now taking a GimpImage object instead. The PDB is still passing around an id only over the wire. But we create an object for plug-ins to work on. This is quite a huge API break, but is probably the best bet for the future quality. It will make nicer API instrospection (and nicer API in binding), will fix the issues with pspec on GimpImageID in Python bindings (which makes the current Python API unusable as soon as we need to work on images, which is most of our plug-ins!), etc. Also it will allow to use signals on images, which will be a great asset when we will finally have bi-directionnal communications (i.e. plug-ins would be able to connect to image changes, destructions, and whatnot).
