This patch sets the kepub reader default margins, i.e. the margins that are used when the adjustment slider is at the far left position. I haven't tested every permutation, but it seems to affect the following margins:

- kepub minimum left/right margins in normal reading mode
- kepub minimum left/right and top/bottom margins in full-screen reading mode

The example values in the patch make the minimum kepub left/right margins similar to the default epub margins. If you set the patch values to zero and remove any margins from the book itself, then the text will go to the very edge (and in full-screen reading mode, to the very top/bottom) of the screen.

Edit: I'd be interested to hear how this patch works on devices other than the Glo: In particular, does it make the Aura's font cut-off problem worse?
