Closes #248

Currently, we adjust the adjust the transform of layer entities to account for the following:

  • bevy_ecs_tilemap anchoring tiles to their center (we need to cancel this out to make all layers of different sizes stack on top of each other nicely)
  • layer offset values

However, for more niche cases of using a layer grid size that differs from the tileset tile size, this isn't sufficient. We also need to adjust the layer's transform to account for the following:

  • the difference between the layer size and grid size causing tiles to sink below the origin with default pivot
  • tiles having an in-LDtk pivot (anchor) value (which makes no difference when tile size = grid size)

This PR makes these additional adjustments. It also makes some stylistic changes that I hope will make some of the mathematical logic more clear.

The plugin still doesn't handle cases where tile size is not divisible by grid size. LDtk does spit out a warning in these scenarios though, so I think it is more reasonable to leave this unsupported for the time being.
