[wxVTK] wxVTK X11 fix

[David A. <da...@gr...>]

Hi there,

I just thought I would report a typo in wxVTKRenderWindowInteractor.cxx

Line 315:
#if defined(__WXGTK__) || defined(__WXX11)
    should be:
#if defined(__WXGTK__) || defined(__WXX11__)

(The two trailing underscores were missing.)

This has been causing wxVTK to fail on X11.

Cheers!

Dave
