This one satisfies at least the styling conditions (in Firefox and Chrome):
* The canvas has 80% width
* The canvas has 50% height (This one worked in Firefox only after 
setting height 100% on body and html. Strange...)
* Resizes when the browser resizes
* Is centered
I only couldn't figure out the  "Always draw a non-aliased pattern of 
lines" part in Firefox. I tried some stuff, but it didn't work.
