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/private include/wx/protocol include/wx/unix src/aui src/common src/generic src/gtk src/msw src/osx src/unix git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@7380 8ced0084-cf51-0410-be5f-012b33b47a6e
