Please Center the Crosshair

Currently, the crosshair that appears to help you aim is at least 1 pixel off, with the disparity increasing as you increase the scale of the GUI. This is super misleading when you're trying to hit something, and could even make you miss hits, especially long-range bow shots.

The fix:

Increase the resolution of the icons.png file from 256x256 to 512x512, and move the crosshair's position in it's area to be centered.

Please fix this, it takes less than a minute to do the fix I suggested, because in Blockbench you can copy/paste the old file and scale it to fit the new resolution. I've even actually done this myself.
