Hi Alexander,

I have just merged your submissions and am now testing it under Linux.
 My goal with this functionality is for the feature to work
consistently across platforms, and this should possible even it does
require a lit to and fro between us and others about what way to
tackle this under different platforms.

In my testing with osgkeyboard, and using debug message in
GraphicsWindowX11::adaptKey() that reports the different values of the
key codes returned I've found that the virtualKey code when I press
the 'A' or 'a' key is 'a', while the previous key symbol code was just
'A'.  So we have progress.  I was expect X11 to return a 'A' rather
than 'a' for the unmodified key symbol, but I guess this makes sense.

This finding makes me wonder what you are seeing for the "virtual key"
when you press "A" and "a" under Windows.  I note that you've used a
specific mapping to a new enum value which use 'A' so I suspect that
we may have divergence between X11 and Win32 here.   What "virtual
key" values are you getting under Windows when press 'A' and 'a'?

Another area I'd like to clear up is that you have adopted the windows
naming of virtual key, this doesn't really have any meaning under X11
or Carbon/Cocoa, and it seem counter to that fact that your "virtual
key" is actually closer to unmodified keycode than the fully modified
keycode that have been returning from osgGA previous, so rather than a
"virtual key" it's actually closer the physical key.   So naming this
property "VirtualKey" doesn't seem helpful for end users save for the
ones already used the peculiar naming adopted in low level MS Win32
functions.  Perhaps "UnmodifiedKey" or another naming would be more
appropriate.

Finally we'll need to do something about OSX as just returning "0" for
the "VirtualKey" will certainly lead to some awkward cross platform
behavior if users adopt this new property.  We can do a call to the
community for implementations under Cocoa and Carbon, I would suggest
we nail the conventions and the naming first though.

Thanks in advance for you thoughts,
Robert.
