Toroidal World

Added

• A new Cylinder world shape: the world loops along one axis — X or Z — and goes on forever along the other; its Nether and End loop on that same axis.
• The World Shape row explains each shape in a tooltip.

Compatibility

• JourneyMap and Xaero's maps draw a Cylinder world folded along its looped axis only, with the seam line there and nowhere else.
• Both fullscreen maps repeat the world across the whole window when zoomed out, with the seam line on every copy; zooming out stops where the world would fall under 64 px wide.
• Xaero's World Map draws the Footsteps trail inside the world on both sides of the world's edge, and the hovered-chunk square stays under the mouse over a neighbour copy of the map.

Fixed

• A relative teleport of more than one world width lands the client on the same copy of the world as the player.
• A nether portal straddling the world's edge brings you out at the matching spot of the portal on the other side instead of at its far end.
• A honey block a piston pushes across the world's edge drags the mob or player standing on it.
• Landing particles at the world's edge appear under your feet instead of at the far side of the block.
• Spear hits and the sulfur cube's push no longer land with world-width force right after crossing the world's edge, and the walking animation no longer stutters there.
