Previously when working on Visual Studio support I noticed an XRC error
dialog when adding the game area to the BoxSizer.
I tried removing the wxEXPAND flag with insufficient testing, the flag
is actually necessary.
The error is actually an incorrect debug assertion that is present in
3.1.2 and later fixed in master. The assertion is not triggered when
the project is built in release mode.
Remove the windows conditional code that removes the wxEXPAND flag.
TODO: silence assertion in debug mode or patch the wxWidgets vcpkg port.
