This change is part of multilayer select feature of v3. Only fixes ScriptFu plugins, not Python or C. Only fixes calls to file load/save procedures and other plugins already multilayer capable. Any future PDB procedures changed to have multilayer signature will require changes to all callers. The new code is verbose: "drawable" => "1 (vector drawable)" Issue 5919 proposes a change to the PDB that would make this less verbose: "drawable" => (vector drawable)" (without the number of drawables) Tested that changed procedures will interpret without syntax errors, on one path. Did not test each changed procedure for functional correctness.
