user32: add a test for window width and height fixup when width or height exceed a short storage or are negative.

[Pierre d'Herbemont]

This is a test for the CreateWindow call to see what is done with width 
or height that exceed the size of a short storage, or are negative. 
Hence we could decide if the fixup should be moved in user32 from 
winex11.drv.

This test is passing under Wine, but I didn't test with real Windows, so 
I guess I better monitor:
http://test.winehq.org/data

Is that the best way to go?

Pierre.
