Document limitation in Cocoa cursor handling.
It seems there is a bug in AppKit which will automatically reset a
cursor even when it is grabbed, but won't reset it when it's brought
back into the window. The upshot of this is that doing a setCursor()
inside of mouse handling behaves slightly different than on the other
platforms (including Carbon). However, we are at the mercy of Cocoa here
and I would rather have all the other things AppKit does right and live
with this bug which they may fix some day.
