[Laszlo-dev] How to make canvas adaptive on its size?

[Raju Bitter]

Actually the Laszlo Systems home page shows that behavior. There are  
scroll bars inside the application, and once you reach the minimum app  
size the scrollbars will show.

I build that app, but the approach we took there was not to make the  
canvas larger, but to place a view inside the canvas which is larger  
than the canvas - with a minimum width and height. You can use that  
approach as work-around for now.
