* libgimpwidgets/gimpscrolledpreview.[ch]: new function: gimp_scrolled_preview_set_position () to set the position of the preview content wrt the drawable. This function might be moved to a virtual function of GimpPreview in a near future. * libgimp/gimpdrawablepreview.c: use this function, so a preview remembers its position from one invocation to the next. This is done using the current executable name as a key for gimp_set/get_data () so each plug-in can have its preview on a different place. More informations could be saved this way: the update toggle, the checks, etc. Addresses bug #162286. * libgimpwidgets/gimppreview.c: smallish cleanup.
