No truncation errors this time

When you go into the option menu, there is a slider for blocks X and Y position. Moving either slider has no effect on the blocks position until the slider is all the way across to 1.0. At that point the blocks will snap across to the opposite side of the screen. i.e. at 1.0 the X position snaps across to the right side and the Y position snaps to the bottom. I *think* this worked in the previous version (i.e. the sliders slowly moved the blocks across the screen). Moving the sliders back just one notch from 1.0 snaps the blocks back to their default sides.
