- New GimpLabelIntWidget which is a label associated to any widget with
an integer "value" property.
- New gimp_procedure_dialog_get_int_combo() which creates a labeled
combo box from an integer property of the GimpProcedureConfig.
- Renamed gimp_procedure_dialog_populate*() with
gimp_procedure_dialog_fill*(). Naming is hard! I hesitated using
_pack() as well (similarly to GtkBox API).
- New gimp_procedure_dialog_fill_flowbox*() functions to create a
GtkFlowBox filled with property widgets (or other container widgets as
we can pack them one in another). This is an alternative way to build
your GUI with sane defaults, with list of property names.
