The typical Mac focus model is that the active window responds to events like mouse-moved and mousewheel, and inactive windows generally do not.  Right now, we implement more of a Windowsy focus model, in which al windows respond to all events all the time.  (When the app is inactive, the OS doesn't deliver any events.)

Our current behavior is un-Mac-like, and there are also a few related bugs (some of which are also present in other widget toolkits): when the app or a window is activated by means other than the mouse, no new mouseover occurs; when you mouse off the edge of one (active) window over a different (inactive) window, the mouse-moved event still goes to the active (wrong) window for the first pixel using the coordinates in the inactive window.

Compare the mouse-moved and scrollwheel behavior to Safari, which does not handle mouse-moved or scrollwheel events for the non-main window.  In some ways, we'll get some of this behavior with Cocoafox because Cocoa doesn't ordinarily send these events to inactive windows.  I'm considering doing this as a 1.8-generation platform-polish improvement too.
This is handled primarily by giving each window its own event dispatch handler, instead of allowing all windows to share one global handler.  I'm concerned about behavior in some of the instances where background windows should respond to events, such as drags to and from background windows.  (Those do seem to be OK.)

Give each window its own event dispatch handler


as an aside....

 if (KeyDown(0x39))	// press [caps lock] to start the profile

should we just go ahead and remove these?

Checked in on trunk, will bake a little bit before going for 1.8[.1].  I also removed the PINK_PROFILING_ACTIVATE chunks from nsMacEventHandler.
