[General] Other browsers

[Krzysztof Palacz]

Hi,
	We've seen this problem in Opera but not in Firefox so far. I believe  
this might be a timing issue, we may be asking for the size of the  
screen available to LK before the browser has fully computed it. This  
would explain why the same Firefox behaves differently on different  
machines.

If you look in index.xhtml, the top level SVG element declared in it  
has the attribute height="%100". If you hardcode a concrete value of  
height, say, 800pt, it'll likely work as expected. We have some  
workaround code in main() that tries to detect when height is less  
than 100, but apparently fails in your case (perhaps because somehow  
FF decided that 100% height means 150pt, which happens to be less than  
100).

Frankly I don't know if this is the problem with SVG implementation in  
Firefox or my lack of understanding of timing aspects of the spec, so  
I'm not sure what the right solution would be. I could try to change  
the threshold value in main() from 100 to 200, although I can't  
reproduce the problem so I wouldn't know if the fix works. It won't be  
any uglier than the workaround we already have in place :)
