// We have a dual implementation for each tool, ControlRef and HIToolbarItemRef

// when embedding native controls in the native toolbar we must make sure the
// control does not get deleted behind our backs, so the retain count gets increased
// (after creation it is 1), first be the creation of the custom HIToolbarItem wrapper
// object, and second by the code 'creating' the custom HIView (which is the same as the
// already existing native control, therefore we just increase the ref count)
// when this view is removed from the native toolbar its count gets decremented again
// and when the HITooolbarItem wrapper object gets destroyed it is decremented as well
// so in the end the control lives with a refcount of one and can be disposed of by the
// wxControl code. For embedded controls on a non-native toolbar this ref count is less
// so we can only test against a range, not a specific value of the refcount.
