 * may be to have a second embedding control responsible for drawing borders
 * and backgrounds eventually)
 * so all this border calculations have to be taken into account when calling
 * native methods or getting native oriented data
 * so we have three coordinate systems here
 * wx client coordinates
 * wx window coordinates (including window frames)
