Continuation of Issue 210:Bottom pixels not complete visable in some zoom modes. I chose to have a dead zone at bottom of zoomed area only when it's at bottom of image too. The dead zone is created only if the remaining space is <= 50 of a normal zoomed line, So the usable pixels are guaranteed to be > half a normal line, and the dead space is always <= half a line.
