Until the image is drawn, you can't really know `top` and `left`.
For instance, let's say you're using percentages:
Shoes.app do
o = oval :top => "50%", :left => "50%", :radius => 20
para "Oval is at (#{oval.top}, #{oval.left})"
end
Until we compute the window size, the coordinates can't be shown.
So, what you do is get the coordinates in the `start` block:
Shoes.app do
o = oval :top => "50%", :left => "50%", :radius => 20
start do
para "Oval is at (#{oval.top}, #{oval.left})"
end
end
Because the start block runs after the first paint.
It still feels like a bug, but I'm not sure if I want to recompute
every slot each time a new element is added. I will probably have
`top` and `left` and `width` and so on return exceptions if you
try to use them before the window is painted... I don't know.
