Rationale: Jeff has a 19" 1280x1024 LCD monitor. When he wants to read text, he
likes to be actually able to read it at maximum size, taking the whole screen
(because you are supposedly not doing anything else meanwhile).

Currently, he has to manually maximize each document he opens, and finds that
very annoying. Besides, having the document automatically maximized has some
other usability benefits :
- it does not cram itself in the upper-left corner of the screen if other
windows are open
- the scrollbar on the right gets easier to use, because you can ram your mouse
on the right screen edge and hit the scrollbar very easily.

Please see these two screenshots. The first one represents the default space
used by epiphany to display PDFs.

The second represents the space that could be "put to profit" and allows much
easier reading.
