My original reason for suggesting this is because I think that the image based 
test is to fragile.  If one single pixel is moved or changed just a little 
bit, the test is failing.  It can also sometimes be difficult to see small 
differences in pictures.

Since the dump of the layout will be text based, it will be much simpler to 
spot differences.

I guess I see it as an addition rather than a replacement. The picture 
approach is probably easier to create but more difficult to evaluate. Or not. 
I'm not sure.

Btw, are you going to produce a picture per page or one huge picture per 
document?
