Mac: Another attempt at fixing the drawRect issue, the last fix resulted in more needsDisplay exceptions in other applications. This fix is not perfect, but it results in correct display and no exceptions. However in the test app, the one render does not always update until you stop moving the scroll bar. Will leave this implementation until a better fix is found.
