Items displayed in shelves aren't equally spaced

When placing items into the newly added shelf blocks, they aren't spaced equally on thirds, but instead slightly squashed toward the middle. This means that, when placing several shelves beside each other, there will be an unusual gap after every 3 items. My guess is that this was done to align better with the pixel grid of the texture, but it actually just looks off. Having the displayed items be equally spaced would make a much cleaner look when placing down several shelves, and would allow for better word displays using custom letter-banners. I see no downsides to changing this.
