This is the same as iframe-transform-nested.html except that the
iframes are cross-process rather than being from the same site.

This page includes frame/nested-cross-process-frame.html in an iframe,
and that page includes frame/box.html in an iframe.
Both pages absolute-position the iframe and give it a scale
factor of 2.0.

The image in box.html is at (10, 10) size (100 x 50)
Relative to nested-frame.html it's at (120, 20) size (200 x 100)
Relative to this file it's at (240, 140) size (400 x 200)
