As usual, I started out intending to do as little as possible
to this to get it working and wound up going overboard.
However, I believe it does allow easy management of the effects
and this will provide a basis for the full blown plugin manager
dialog.
This brings the builtin, LV2, and VAMP effects inline with the
Audio Units, LADSPA, and VST effects. All effects now share
a common UI.
This gives all effects (though not implemented for all):
User and factory preset capability
Preset import/export capability
Shared or private configuration options
Builtin effects can now be migrated to RTP, depending on algorithm.
LV2 effects now support graphical interfaces if the plugin supplies one.
Nyquist prompt enhanced to provide some features of the Nyquist Workbench.
It may not look like it, but this was a LOT of work, so trust me, there
WILL be problems and everything effect related should be suspect. Keep
a sharp eye (or two) open.
If you can believe it, this whole big mess is
just to get localized effect labels back into
the menus.
I sure wish I'd had a little bit more time to
finish up all of the effects. It sure would
be a lot cleaner (code wise).
