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).
The hairbrained "solution" I came up with in r13716
"worked" but it was simply unnecessary and this is
what I should have just done to begin with.
The previous "solution" actually caused some display
issues in the menus.
The problem is that lookup of effects is based on their
ID and legacy effects didn't play well in this scheme, so
I've added a workaround for now. This will go away when
I get all of the effects converted.
And removes some debugging.
