[chuck-users] Oscillosope UI

[Spencer Salazar]

Hey Mario-

Yep, Perry's got the right idea. The big cleanup in the ChucK 1.4 update
left out a component that had been built to support GUI chugins, but two
alpha-status examples you can look at are MAUI.chug and chugl (ChucK GL).
These are currently Mac only.

I recently spent a little time reimplementing support for these GUI
chugins, which works in the current master branch of ChucK or will work in
an upcoming 1.4.0.1 release that is being prepared soon.

The basic idea is that most GUI frameworks expect to operate on a main
thread of sorts. Chugins that want to run a GUI can submit a hook/callback
for chuck to call in its main thread, which is otherwise
mostly idle (chuck's VM and audio synth are running in a separate real-time
audio thread).

There are other considerations such as what happens if two GUI chugins
compete with each other, how GUI chugins are meant to work in miniAudicle,
Windows/Linux, etc. But the basic idea is there / not crazy!
