+@li @b "Size": this is the current size of the window and it can be explicitly
+ set or fetched with the wxWindow::SetSize() or wxWindow::GetSize() methods.
+ This size value is the size that the widget is currently using on screen and is
+ the way to change the size of something that is not being managed by a sizer.
+
+@li @b "Client Size": the client size represents the widget's area inside of any
+ borders belonging to the widget and is the area that can be drawn upon in a
+ @c EVT_PAINT event. For wxFrame, the client size also excludes the frame
+ menu, tool and status bars, if any. If a window doesn't have any border
+ (and is not a wxFrame with some bars) then its client size is the same as
+ its size.
