Title: Update Screen.cpp

Screen buffer address MUST be divisible by 8.
If that's not the case, the display will be slightly shifted to the right.

The current nPDF version does not check this.
So when the additionnal screen buffer gets an address not divisible by 8, there will be a display problem once every 2 refreshes because of the double buffering.
