Title: Lots of patches makes the draws to layered view take a long time

This is strange. Try this code (in `/wolfsheep` or something):

to setup
ca
resize-world -100 100 -100 100
crt 1
reset-ticks
end

to go
ask turtles [
fd .1
]
tick
end

Run it and profile. When you check the profile results, you'll see that the `drawImage` calls in `LayeredView` are taking a really long time. We may want to toss the `LayeredView` altogether, and just position the layers on top of each other.
