annotate widgets/Panner.h @ 56:fedaf3ffe80a

* Add menu for re-adding existing layers * Fix layer tree window so that it at least approximates correct * Add bundled operations in command history, for use with things like multiple consecutive changes to a parameter value * Disambiguate plugins that happen to have identical descriptions * Add spectral centroid plugin (could use some parameters!) * Some other fixes
