Fixes the annoying bug where the center of the crosshair doesn't actually match the center of the screen.
Example (Red Cross = Screen Center):
| Vanilla Minecraft | With the Mod |
|---|---|

 |
If the crosshair is an uneven number of pixels wide (e.g. 3), it will still be offcenter but just by half a pixel.
This also works with any crosshair-changing resource packs!
