-Note that in wxWidgets 2.9 and above, wxBORDER\_THEME is defined to be 0 and it is not necessary
-to pass the border style explicitly: wxWidgets will deduce the correct border style itself if there
-is none supplied. Because of the requirements of binary compatibility, this automatic border
-capability could not be put into wxWidgets 2.8 except for built-in, native controls. So in 2.8, the border
-must be specified for custom controls and windows.
-
-Since specifying wxBORDER\_THEME is defined as 0 and is the equivalent of abstaining on the
-border style decision, on non-Windows platforms a suitable border style will be chosen.
+In general, specifying wxBORDER\_THEME will cause a border of some kind to be used, chosen by the platform
+and control class. To leave the border decision entirely to wxWidgets, pass wxBORDER\_DEFAULT.
