Update on LV2 plugins for cin5 follows.
I noticed the following with the new Calf plugins. The parameter windows of
> the Calf plugins are not resizable.
This morning's GIT checkin fixed the resizing.

OR hook up an interface that was developed over many years can not be done
in a short period of time.

> Well, gg and I looked all over the internet for some way to hook up the
Calf GUI's to have the above capability, but to no avail. So for now we
are tabling this effort with the hope that future ideas or help arrives.

> Until some information/documentation becomes available, not going to be
able to do this. But it took less than 1 hour to add a pot and slider bar
so that when you highlight a specific parameter, you can change its value
right away. That works differently than the text box where you have to key
in a value and then press "apply" before it takes effect.
The current code will be usable only by users who do their own builds WITH
the proper libraries (liblilv and Calf) are installed. The monthly builds
will no have the option unless someone specifically requests it with the
idea that it is usable in the current form.
