Ardour seems to listen to the bounds of the plugin window, and will call
`onSize` on the plugin editor when move/resize events are sent to the X
window - even if the size of the window didn't really change. This can
result in an infinite resize loop, where calling `onSize` on the VST3
instance sends a resize event to the plugin window, and this event
causes Ardour to call `onSize` on the plugin view.

To get around this, the Linux ComponentPeer will no longer request a
bounds change from the window system if the requested bounds are the
same as the current bounds.
