If the final width and height don't match the width and height passed into setBounds the platform needs to call notifyResize to correct the window's properties. This happens naturally if the window size actually changes since that will trigger the OS to send size change notifications. If the platform window size doesn't change the OS notifications won't trigger. We need to catch that case and send notifyResize anyway.

This looks reasonable although I haven't tested it. I left one question inline. I presume you have run all systems tests?

modules/javafx.graphics/src/main/java/com/sun/glass/ui/win/WinWindow.java line 161:

Could this lead to two resize commands in some cases? I can see why this new logic is needed for the case where the window was already at max (or min) width and height, but if it wasn't already constrained, wouldn't the resize event have already happened?
