1026 * ---------- Cursor clipping methods ----------
1027 *
1028 * Neither Quartz nor Cocoa has an exact analog for Win32 cursor clipping.
1029 * For one simple case, clipping to a 1x1 rectangle, Quartz does have an
1030 * equivalent: CGAssociateMouseAndMouseCursorPosition(false). For the
1031 * general case, we leverage that. We disassociate mouse movements from
1032 * the cursor position and then move the cursor manually, keeping it within
1033 * the clipping rectangle.
1034 *
1035 * Moving the cursor manually isn't enough. We need to modify the event
1036 * stream so that the events have the new location, too. We need to do
1037 * this at a point before the events enter Cocoa, so that Cocoa will assign
1038 * the correct window to the event. So, we install a Quartz event tap to
1039 * do that.
1040 *
1041 * Also, there's a complication when we move the cursor. We use
1042 * CGWarpMouseCursorPosition(). That doesn't generate mouse movement
1043 * events, but the change of cursor position is incorporated into the
1044 * deltas of the next mouse move event. When the mouse is disassociated
1045 * from the cursor position, we need the deltas to only reflect actual
1046 * device movement, not programmatic changes. So, the event tap cancels
1047 * out the change caused by our calls to CGWarpMouseCursorPosition().
