It's not clear to me why (200,200) becomes (92,162) and not (100,170). Any clue
what causes the 8-pixel gaps? Padding may be? Please try to position the iframe
using top/left, and set margin=padding=0.

Default body margin is 8px, I like to set body { margin: 0px; } in tests for
nice round numbers.
