+// DoSetSizeIntr and DoMoveWindowIntr
+// PROBLEM:
+// under Motif composite controls (such as wxCalendarCtrl or generic wxSpinCtrl
+// did nott work and/or segfaulted because
+// 1) wxWindow::Create calls SetSize,
+//    which results in a call to DoSetSize much earlier than in the other ports
+// 2) if wxWindow::Create is called (wxControl::Create calls it)
+//    then DoSetSize is never called, causing layout problems in composite
+//    controls
+//
+// SOLUTION:
+// 1) don't call SetSize, DoSetSize, DoMoveWindow, DoGetPosition,
+//    DoSetPosition directly or indirectly from wxWindow::Create
+// 2) call DoMoveWindow from DoSetSize, allowing controls to override it
