Import r67258 of the wxWidgets trunk, which I expect will before

long become wxWidgets 2.9.2, which in turn is expected to be the
last 2.9 release before the 3.0 stable release.

Since the full wxWidgets distribution is rather large, I have
imported only the parts that we use, on a subdirectory basis:

art
include/wx/*.*
include/wx/aui
include/wx/cocoa
include/wx/generic
include/wx/gtk
include/wx/meta
include/wx/msw
include/wx/osx
include/wx/persist

include/wx/unix
