The code is not doing a simple replace of one method with the other, so the commit message shouldn't say it is. thanks -- PMM

The NSEvent class method scrollingDeltaY is available for Mac OS 10.7 and newer. Since QEMU supports Mac OS 10.5 and up, we need to be using a method that is available on these version of Mac OS X. The deltaY method is a method that does the same thing as scrollingDeltaY and is available on Mac OS 10.5 and up. So we simply replace scrollingDeltaY with deltaY.
