What is the xawt sizer wrapper, really?

That's something for Artem and other AWT folk to consider.

As I said we manage to work with this for cross-compiling by simply 
building and running on the build host to get the data for the target 
(which as far as I know is not OS specific - but I don't have absolute 
confirmation on that). The only glitch we had was that when we started 
cross-compiling on 64-bit linux it generated 64-bit data for a 32-bit 
target (oops!) - but that was easily fixed.
