output maximizing

iTunes window has 4 px margin on every side when maximized.

It is the same for 32 and 64bit iTunes.

I tested on two different machines both with Ubuntu 16.10 64bit. Same result
with KDE Plasma 5, MATE and Cinnamon. Same with builtin and native gdiplus.

Output when I click maximize button, see attachment.

I don't know if I missed that before, because I didn't really maximized iTunes
that often before. Now I tested with rc3-5 and it is the same result.
