+// I don't think this class belongs in WebKit. Lets move it out.
+// Things that I've never bothered working out:
+// For non-sheet windows, handle Carbon WindowMove events so as to do the same things as -[NSWindow _windowMoved].
+// Check to see how this stuff deals with various screen size change scenarious.
+// M.P. Warning - 9/17/01
+// There are some invariants I'm maintaining for objects of this class which have been successfully initialized but not deallocated.  These all make it easier to not override every single method of NSWindow.
+// _auxiliaryStorage->auxWFlags.hasShadow will always be false if the Carbon window has a kWindowNoShadowAttribute, and vice versa.
+// _auxiliaryStorage->_auxWFlags.minimized will always reflect the window's Carbon collapsed state.
+// _borderView will always point to an NSCarbonWindowFrame.
+// _contentView will always point to an NSCarbonWindowContentView;
+// _frame will always reflect the window's Carbon kWindowStructureRgn bounds.
+// _styleMask will always have _NSCarbonWindowMask set, and will have NSClosableWindowMask, NSMiniaturizableWindowMask, NSResizableWindowMask, and/or NSTitledWindowMask set as appropriate.
+// _wflags.oneShot and _wflags.delayedOneShot will always be false.
+// _wFlags.visible will always reflect the window's Carbon visibility.
+// _windowNum will always be greater than zero, and valid.
+// The instance variables involved are ones that came to my attention during the initial writing of this class; I haven't methodically gone through NSWindow's ivar list or anything like that.  M.P. Notice - 10/10/00
+// Things that have to be worked on if NSCarbonWindows are ever used for something other than dialogs and sheets:
+// Clicking on an NSCarbonWindow while a Cocoa app-modal dialog is shown does not beep, as it should [old bug, maybe fixed now].
+// Handling of mouse clicks or key presses for any window control (close, miniaturize, zoom) might not be all there.
+// Handling of miniaturization of Carbon windows via title bar double-click might not be all there.
+// The background on NSCarbonWindowTester's sample window (not sample dialog or sample sheet) might be wrong.
+// The controls on NSCarbonWindowTester's sample window look inactive when the window is inactive, but have first-click behavior.
+// M.P. Warning - 12/14/00
+// Some things would have to be made public if someone wanted to subclass this so as to support more menu item commands.  M.P. Warning - 9/19/00
