Cover thumbnails in standby are not correctly resized.

[GoogleCodeExporter]

Your model / PRS+ version?

PRS 650 / Nightly R.068

What steps will reproduce the problem?
1. Open attached book. (It's a ripped version, just the cover, from a legally 
owned ebook).
2. Enable cover thumbnail in standby.
3. Go to standby.
4. Instead of the full cover, you'll see just a small part of it (In fact, the 
upper middle section of the cover without any resizing so just ..os..).
