/*
* ---------- Cursor clipping methods ----------
*
* Neither Quartz nor Cocoa has an exact analog for Win32 cursor clipping.
* For one simple case, clipping to a 1x1 rectangle, Quartz does have an
* equivalent: CGAssociateMouseAndMouseCursorPosition(false). For the
* general case, we leverage that. We disassociate mouse movements from
* the cursor position and then move the cursor manually, keeping it within
* the clipping rectangle.
*
* Moving the cursor manually isn't enough. We need to modify the event
* stream so that the events have the new location, too. We need to do
* this at a point before the events enter Cocoa, so that Cocoa will assign
* the correct window to the event. So, we install a Quartz event tap to
* do that.
*
* Also, there's a complication when we move the cursor. We use
* CGWarpMouseCursorPosition(). That doesn't generate mouse movement
* events, but the change of cursor position is incorporated into the
* deltas of the next mouse move event. When the mouse is disassociated
* from the cursor position, we need the deltas to only reflect actual
* device movement, not programmatic changes. So, the event tap cancels
* out the change caused by our calls to CGWarpMouseCursorPosition().
