## About The Pull Request All usages of world.icon_size in code have been replaced with new `ICONSIZE_X`, `ICONSIZE_Y` and `ICONSIZE_ALL` defines depending on context Replaces some "32" magic numbers with the defines A few bits of code have been modified to split up x/y math as well ## Why It's Good For The Game Magic number bad, code more readable, code more flexible and I'm told there's an access cost to doing world.icon_size so minor performance gains ## Changelog 🆑 tonty code: made some code relating to the world's icon size more readable /🆑 --------- Co-authored-by: Ghom <42542238+Ghommie@users.noreply.github.com>
