+// General remark:
+// wxRegion is always basically stored in wx coordinates. However, since
+// OS/2's internal functions rely on "top > bottom", the values of top and
+// bottom values of a region need to be interchanged, as compared to wx.
+// This needs to be taken into account when feeding any rectangle to wx _or_
+// when accessing the region data via GetBox, wxRegionIterator or otherwise.
