The list of objects where the config object is a dedicated custom class (instead
of a runtime-registered class) is well known. These are the operations
registered inside gimp_operations_init().
The list inside gimp_gegl_procedure_execute_async() which the previous commit
was updating was not right: it was still missing "gimp:hue-saturation" and
"gimp:threshold" should not have been on the list (this was generating a
CRITICAL when trying to get the "config" property on this object).
Instead let's add some init/exit() functions in gimp-operation-config API to
distinguish the operations with custom config (registered during init) with all
the others. Then we add gimp_operation_config_is_custom() which can be used
everywhere where we want to verify if an operation is using a custom-made config
object or a generated class just mirroring the operation properties.
This way, we should not get out-of-sync anymore.
which is the same as g_object_class_list_properties() but filters
out the properties for which we don't want to create a GUI.
Use it in gimp_prop_gui_new().
Return only the config object's GType and do the g_object_new() in the
caller (one caller only needs the type, there is no need to create a
dummy object just to get to its type).
Filters settings used to be serialized and deserialized only
when a filter tool's GUI was shown, too late for the code that
re-runs/re-shows filters with previous values.
Move the entire loading/saving code to gimp-operation-config.c, even
adding/removing the dummy separator item between timestamped automatic
history and manually saved settings. Load the settings automatically
when a settings container is requested, but still trigger saving from
the few places the container is changed in the GUI; could also
automate that later.
This commit also moves all settings of filters that have their own
tools from gimpdir/tool-options/ to gimpdir/filters/. Add compat code
to try the old filename if the new doesn't exist, so files are
migrated automatically.
WIP, but this step already fixes the bug.
