Fixed window size for ReaPlugs

[kitterion]

I'm using 64-bit reaper VST plugins with carla on linux through carla wine bridge. For some reason the window size for each of them (except ReaControlMIDI) is fixed to 400x300 which makes it really difficult to configure some of the plugins.

Here's a few examples.

I'm running KDE neon 16.04 lowlatency with kxstudio repos.

Carla 1.9.8 (2.0-beta6)
Python version: 3.5.2
Qt version: 5.9.3
PyQt version: 5.9.2
wine-2.0.1

This is normal. VST plugins are not resizable by the host by design.
Usually plugin UIs handle the resizing.

The fixed size of the UI is reported by the plugin, the host shows creates a window with a size that matches it.

Hm. It used to be working somehow a few months ago.
I'm willing to dig into this and have a look if there's anything that could be done. So would you accept a PR in case I find a workaround for this?
If you think this is a non-issue feel free to close it.

the code that handles windows vst plugins is completely different from the last release.
(the big juce-removal change)

maybe they implement the custom stuff to handle host-side resize.
I can check this later on, I know there is something out there for it.

For whatever reason this bug doesn't happen anymore for me, everything looks fine.

I know the reason, because I fixed it in 90c7f8a :)

I have been on a bug-hunting spree, adding some small new things but making sure old stuff works nicely.
damn macOS is making it hard though errrr
