// calling -[className] on the content views of NSWindow, NSTabItem, and NSBox all return NSView, so I'm assuming I just need to override these
// fornunately:
// - NSWindow resizing calls -[setFrameSize:] (but not -[setFrame:])
// - NSTab resizing calls both -[setFrame:] and -[setFrameSIze:] on the current tab
// - NSTab switching tabs calls both -[setFrame:] and -[setFrameSize:] on the new tab
// so we just override setFrameSize:
