1.2 Quartz video: Ripped out QuickDraw and QuickTime.

There are several other 10.6 fixes in here, too...now we can build a 64-bit
SDL for Snow Leopard!

-        In order to determine if a direct copy to the screen is possible,
-        we must figure out if there are any windows covering ours (including shadows).
-        This can be done by querying the window server about the on screen
-        windows for their screen rectangle and window level.
-        The procedure used below is puts accuracy before speed; however, it aims to call
-        the window server the fewest number of times possible to keep things reasonable.
-        In my testing on a 300mhz G3, this routine typically takes < 2 ms. -DW
-    
-    Notes:
-        -Calls into the Window Server involve IPC which is slow.
-        -Getting a rectangle seems slower than getting the window level
-        -The window list we get back is in sorted order, top to bottom
-        -On average, I suspect, most windows above ours are dock icon windows (hence optimization)
-        -Some windows above ours are always there, and cannot move or obscure us (menu bar)
-    
-    Bugs:
-        -no way (yet) to deactivate direct drawing when a window is dragged,
-        or suddenly obscured, so drawing continues and can produce garbage
-        We need some kind of locking mechanism on window movement to prevent this
-    
-        -deactivated normal windows use activated normal
-        window shadows (slight inaccuraccy)
