commit 98b4cfd82bb6c3eb7830b46795dcd6896cfdef76
Author: Henrique Nakashima <hnakashima@chromium.org>

Rewrite PDFiumEngine::Form_GetPageViewRect.

It did not do what was expected of FFI_GetPageViewRect. To start,
it assumed the page requested was the most visible one, which isn't
always true. Most importantly, it returned the bounds of the page
in screen coordinates, when it should be returning the bounds of the
visible portion of the page in page coordinates.

Yeah, Chrome is not currently built with XFA even in dev. We're not there yet. The only way to verify is building it.
