I think that if we define the API between Host and GUI purely in terms of
getting/setting parameters. Then we are free to introduce cross-platform
graphics at any time (even before GMPI 2.0).
If the host just provides an empty window, we can 'drop in' any graphics
routine we like, any time.
Yeah. So maybe we restructure the UI requirements like this?:
Req. 63: Generic (Host-Provided) GUI - <Stuff here about what kind of
widgets the host is expected to support. Maybe also mention compat
with HW plug boxes ala Plugzilla as a goal?>
Req. 64: Custom (Plugin-Provided) GUI - <Stuff here about how this is
not part of 1.0, but if you were looking for a rough idea of what
it'd be like, vstgui would be a good model>
On the other hand, are we sure param get/set a rich enough model for
communication between the custom GUI code and the DSP code? I'm
thinking about some of the great intricate signal displays we're
seeing these days, seems like they could, perhaps, be needlessly
cumbersome to express in those terms.
Hmm, just noticed VST GUI is open source. Mayby we could adapt it *evil
laugh*.....that would save a LOT of time.

Heh heh, I admit thought about that too. Guess my next question
would be: Do people actually like it, and what're the license terms?
Also, about this...:
"Req 65: GMPI must define a mechanism for out-of-process UIs.
Hosts must support this.
FIXME: Earlier, we asserted that all plugins are native, which means
out-of-process stuff is beyond the scope of GMPI. Do we expect every
plugin with an out-of-process GUI to write their own GUI-to-GMPI
proxy? Or do we standardize out-of-process plugins?"
...I don't understand why native plugs means no out-of-process parts.
There may be multiple processes running on the same box.
