From Paul Melis, "Here is an updated osgviewerWX example to bring it more in line with the

other GUI toolkit examples. It now takes a model file as command-line
argument (complaining if there isn't one), and its startup window size
is now actually applied (it used to be too small). I tested this with a
unicode-build of wxWidgets, as that is the recommended build type on
Linux with GTK. I'm pretty sure this version of the example will work
for the ANSI build as well, but I have no way of testing."
