97 * Right now we have the following setup :
98 * a border that is not part of the native control is always outside the
99 * control's border (otherwise we loose all native intelligence, future ways
100 * may be to have a second embedding control responsible for drawing borders
101 * and backgrounds eventually)
102 * so all this border calculations have to be taken into account when calling
103 * native methods or getting native oriented data
104 * so we have three coordinate systems here
105 * wx client coordinates
106 * wx window coordinates (including window frames)
107 * native coordinates
