Linux Validation Support

[baconpaul]

1. Don't create a message manager in the DSP thread
2. Set validation level to 1 for linux since the leak of a Glyph (run the standalone and quit to see it) holds a timer in UI tests it seems
3. Add the Standalone to the CMake

1. D'oh—good catch. This actually resolves an unrelated issue I found recently.
2. So I take it that the issue is only reproduceable in linux?
3. Nice.

Ah, and also: what do you mean by a Glyph? Is it something to do with fonts?

If do a debug build, you run the standalone and then quit the juce leak detector will give you a leak message. The fact that it is a glyph means you somewhere assign a font to a static or a pointer which leaks or some such.

And I just tested and the error doesn't appear on mac.

I bet it has something to do with https://forum.juce.com/t/lookandfeel-custom-fonts-linux-leaks/53914/5

There's an interesting solution posed here: https://forum.juce.com/t/only-loading-fonts-once-in-a-plugin/49564

Storing fonts in struct deriving from a special juce base class that deletes derived instances on exit...might see about that.

Yeah we used to do that using the juce::DeleteOnExit thing to hold references to all our in memory fonts. We cleaned it up a bit once we had a skin object but that's probably it.

Honestly though meh doesn't matter that much. Run linux at validation level 1 and ship it with this merged. Seems the plugin close to works and linux users will give you good bug reports if it doesn't.

Agreed.
