This is right, there is no way to know if the lua code uses '.' or ':'
(which pushes the self onto the stack) and therefore we don't know if
we should remove it and so the function fails. All static functions
are accessed using the '.' notation and NEVER ':'. Think of it this
way, static class member functions do not need to be called from an
object and therefore you don't use ':' which puts the object on the
stack.

Properties do not work for static functions called on the class table
since they are already pushed into the table. This means that we
cannot automatically try to generate properties and I think it would
be more confusing than anything to also add 'Cwd' to the table. Try
the code below.
for k, v in pairs(wx.wxFileName) do print(k, v) end
SplitPath function: 0152F7C0
GetCwd function: 0152F438
SplitPathVolume function: 0152F860

I have fixed it so that "fn.Cwd" works now, but again, "fn:GetCwd()"
is wrong and simply cannot be made to work reliably unless we can find
out if '.' or ':' was used (which we can't).
I have also rewritten some of the wxlua.html docs to clarify this,
please see the section "C++ Classes CLASS_NAME" and below. Does this
explain things well enough?

Also, there is a complete list of all things possible with the
bindings here. I've hopefully tested everything that is designed to
work in some way or another. If you can think of any more tests that
would be great as I want this program to test everything.
