I was testing some layout-wide cleanup changes and noticed that svgtetris doesn't work on trunk. The bricks do fall in the script, because you lose the game after some time, but nothing is refreshed/painted after the initial paint. I have no idea if this is expected behavior or not, since I do not know SVG I can't read if from the SVG source (maybe it used some workaround or whatever that doesn't work anymore and isn't supposed to either), and thus I'm filing the bug as UNCONFIRMED.

Note that the bug summary says "trunk", but I did not actually check the 1.8 branch. It might be broken there, too (for all I know.)
