comparison plugin/LADSPAPluginInstance.cpp @ 166:702fc936e6a6

* Pull transforms out of Layer menu (again) and into a separate Transforms
  menu
* Add Recent Transforms submenu
* Add effects and generators to the transforms menu (not yet implemented)
  as well as analysis plugins and data-from-effects (control output ports)
* Add a nice dictionary-volume-style alphabetic subdivision of plugin names
  in plugins By Name menus
