I don't fully agree that those lines are "spurious".  Since you only
fill-ed the paths, but didn't stroke them, there are technically
gaps of zero pixel width between adjacent tiles.  And just like lines of 
width zero are not exactly the same thing as no lines at all, gaps of 
width zero are not the same as no gap at all.  For this to be a 
meaningful test, the paths could have to be both filled and stroked.
