wxWidgets/contrib/include/wx/fl/controlbar.h
Mart Raudsepp ccdd4b0b42 wxFrameLayout contains wxPen by value, so the wxPen class declaration from wx/pen.h is required so that the compiler 
would know the size of wxFrameLayout class. Was a problem for projects using wxFL and including wx headers
one-by-one instead of using wx.h.
