/*
|
||
|
|
This runloop connects to X11 VSTGUI, it connects VST3 and VSTGUI together.
|
||
|
|
The Windows and macOS runloops do not need this, the OS-provided
|
||
|
|
functionality is used instead.
|
||
|
|
|
||
|
|
Previously, this was based on VSTGUI code provided by Steinberg.
|
||
|
|
This is replaced with a rewrite, because the original code has too many
|
||
|
|
issues. For example, it has no robustness in case handlers get added or
|
||
|
|
removed within the execution of the handler.
|
||
|
|
|
||
|
|
This version allows to call event processing externally, in case the host
|
||
|
|
has a defective X11 event loop notifier. (some versions of Bitwig do)
