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

[Max Carlson]

It seems full screen mode shows the application at the size specified by the developer. If resizing is desired, percentage values should be used for width/height - whether specified in the query string, html embedding code, orcoming from the canvas.

Yes, I know that the LaszloCanvas code is looking for those args.  
Isn't it like there are 4 sources for the width/height value?

1) canvas attributes
2) embedding code
3) query args for SWF file
4) default values 400/400, in case the query args contain an invalid  
value

But what you are saying means: if a developer wants to use full screen  
feature, he must take caution not pass any values for width and height  
into the app at runtime, or full screen mode might not auto-adjust the  
canvas size.
