 During the transition from Bullet to GodotPhysics in Godot 4, cylinder collision
 shapes had to be reimplemented from scratch. However, cylinder collision shapes
 are one of the most difficult shapes to support, which is why many other physics
 engines don't provide any support for them. There are several known bugs with
 cylinder collision shapes currently.

-character take more space diagonally. Capsule collision shapes do not have this
-downside, but their shape can make precision platforming more difficult.

+    In Godot 4.5 and later, creating a composite collider is automatically done
+    when using a TileMapLayer node. The chunk size (``16`` tiles on each axis
