Issue with AudioProcessorEditor::setScaleFactor

[pflugshaupt]

You should no longer use editor->setScaleFactor(), but use Desktop::setGlobalScaleFactor() now.

UI Scaling

This has changed on the develop branch - the DPI handling code has been refactored for plug-ins to use AudioProcessorEditor::setScaleFactor() internally so calling this from user code will interfere with the host’s transform. There’s some info about the change in the breaking changes doc here, but basically you should use Desktop::setGlobalScaleFactor() if you want to apply a top-level scale transform to the editor window.
