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

[Raju Bitter]

And if you don't want to read the forum post: he attached a width and  
height parameter to the SWF for whatever reason (customer  
requirement), and never expected that to influence the behavior full  
screen.

So my question actually is:
1) is it a documented behavior, that you can override width and height  
with query vars
2) if it's a documented behavior or a "feature", I need to mention in  
the fullscreen documentation what effect it will have
