Several notes.

• It moves a line of code that attempts to center the cursor to begin with, then stops it from being used in SDL tile builds.
  • Why did the original not work? Was it placed in the wrong place?
  • Why does it break tiles? And since it's removed from SDL builds, that means there's no centering there. Will this be an issue?
• https://github.com/CleverRaven/Cataclysm-DDA/issues/45968#issuecomment-742781837 suggests that the change may also impact blinking zone overlays, can we confirm that this issue does not also appear here in either builds?

Based on Olanti's advice, Zlorthishen along with me have decided to try to do work on a port of a much more high quality, bigger scope than this, so there is no need to merge this essentially
