BUG: Vizia resize problem

[aizcutei]

Vizia gui seems cannot resize properly. I tested on both Windows and MacOS. For Windows, standalone window can resize but canvas can't resize. On MacOS, window cannot resize but canvas can resize. I also tested VST3, it has same problem.

I just got a report from @sletz, he has the same issue, on OSX:

On Linux the resizing is only an issue with standalone builds when not using the resize handle (bottom right).
Instead when you use the typical Xorg alt+RMB resize on the nearest corner the same behavior as described here happens:

For plugin builds (VST3 + CLAP) it is only possible to resize with the corner handle, so this all works as expected.

Using the current master version of nih_plug_vizia, the resize handle correctly detects mouse intersection but doesn't resize for VST3 plugin builds in Ardour (though it works correctly under Bitwig). The resize handle works correctly in the previous release of Spectral Compressor 0.4.3 (released March 31 2023) but not for the current master version I compiled, so this is a recent regression.

I'm not sure how Ardour and Bitwig differ in handling plugin window resizing, but the previous implementation worked correctly under both hosts. It would be great if the current version did too.
