// When we are called there may be a queued tracking rect event (mouse entered or exited) and
// we won't know it. A specific example is wxGenericHyperlinkCtrl changing the cursor from its
// mouse exited event. If the control happens to share the edge with its parent window which is
// also tracking mouse events then Cocoa receives two mouse exited events from the window server.
// The first one will cause wxGenericHyperlinkCtrl to call wxWindow::SetCursor which will
// invaildate the cursor rect causing Cocoa to schedule cursor rect reset with the run loop
// which willl in turn call us before exiting for the next user event.
// If we are the parent window then rebuilding our tracking rectangle will cause us to miss
// our mouse exited event because the already queued event will have the old tracking rect
// tag. The simple solution is to only rebuild our tracking rect if we need to.
