Instead of ignoring all `NonlinearVirtual` events. This lets us release
focus when instantly moving the mouse from a plugin GUI to something
else. This generates `NonlinearVirtual` event, and previously we ignored
those because that also happens when opening a dropdown menu in a TDR
plugin (which uses popup windows instead of actual dropdowns).
We'll need this for the `LeaveNotify` because `GetCursorPos()` updates
only once every 100 ms, which means that it would still point to the old
window we're actually leaving.
This will let us detect other, non-wrapper windows to the right and to
the bottom of a plugin GUI. Useful for drag-and-drop so we don't end up
overriding Wine's internal drag-and-drop mechanism.
This is needed for Tracktion Waveform because they shift our wrapper
window a bit downwards. Otherwise opening the window while your mouse
cursor is already inside of it would trip up Wine's coordinates.
We moved this from `parent_window` to `wine_window` in
974951e966 to account for Waveform adding
an offset in their windows, so now that we have `wrapper_window` we
should be translating from there instead.
Wine is weird. The whole reason why we're doing these weird things is
because Wine somehow tries to delete the window twice. If we don't call
`xcb_query_tree()` here (and get an error back), then we're back at the
error we tried to solve. Apparently this works, and given that noone
dares touching Wine's X11drv code I won't ask any further questions.
This reverts commit d3d21c65f4.
On second thought, Wine actually handles things better this way. We want
to avoid both hangs and the Wine window becoming visible, and this
achieves both of those things. We should just silence the warning.
We still need to make sure this window resizes properly, but this should
prevent the host from interacting with the full screen `ConfigureNotify`
events we keep sending to `wine_window`.
This should in theory prevent Nimble Kick from triggering a stack
overflow when the event loop timer procs before `IPlugView::attached()`
gets called and the plugin hasn't been registered yet. I haven't seen
any other VST3 plugins trigger a race condition here.
In some cases we would treat dead processes as not running (we could
also get EAVAIL instead of EINVAL, so it's better to just check the one
thing we should treat as a success instead).
