+ * "the wxImage is already sized for backing scale such and such". )
+ * Unfortunately, the constructor changes the size of wxBitmap too.
+ * Thus We need to use unscaled size value for bitmaps that we use
+ * to avoid scaled size of control items.
+ * For this purpose control drawing methods and
+ * control size calculation methods (virtual) are overridden.
