[Laszlo-dev] Query args width and height processed by LaszloCanvas.lzs#construct()

[Raju Bitter]

Actually it happens on canvas construction, in the construct() method.  
Which means, it overrides the values in your <canvas /> declaration  
within LZX. As a result canvas will - even in full screen mode - still  
report the static width & height passed into the app.
