The new function gimp_procedure_set_sensitivity_mask() allows plug-ins to tell when a procedure should be marked as sensitive or not. gimp_procedure_get_sensitivity_mask() retrieves this information. Currently plug-ins are automatically marked as sensitive when an image is present and a single drawable is selected. Nowadays, we can have multiple selected layers so we should allow plug-ins to tell us if they support working on multiple drawables. Actually we could even imagine new plug-ins which would be made to work only on multiple drawables. Oppositely, there are a lot of plug-ins which don't care at all if any drawable is selected at all (so we should allow no drawable selected). Finally why not even imagine plug-ins which don't care if no image is shown? E.g. plug-ins to create new images or whatnot. This new API allows our core to know all this and show procedure sensitivity accordingly. By default, when the function is not called, the 1 image with 1 drawable selected case is the default, allowing existing plug-ins easier update. Note: this only handles the sensitivity part right now. A plug-in which would advertize working on several layer would still not work, because the core won't allow sending several layers. It's coming in further commits.
