Changing Snap Settings via TileMap may not be intuitive, after all.

Currently, I set up a new node extended from TileMap where setting its tile size would also set the scene's snap settings. But now that I've learned more on using Godot, I'm starting to see that this might not be a good idea:

• Accessing snap settings to edit via script is already difficulty (though I have managed to do it).
• Snap settings are not universal across the whole project; one scene could have different settings from another.
  • Complicating things further are scene instances--I don't know how to account for that.
• I did not account that many game maps could've been made in a single project by creating a base first, then instancing from it. Therefore, if user wants to change the cell size at any time, they could've simply do so at the base.

I will remove the implementations in a future update, but the real is whether the user would depend on snap settings to edit the game map in the first place.

• If so, I could make such that when a new TileMap is added, its cell size is set according to the snap settings.
• Otherwise, I could make moving the PlayingPiece snap according to its parent TileMap. IIRC, this is already done.

In the end, I have made children playing pieces snap in relative to the grid map TileMap, foregoing the conventional snap settings altogether.
