Issue description

I've been playing around with TileSets / Tilemaps and just want to document the issues I faced.

My Test Tileset:

(1) Documentation Missing: Current documentation doesn't say if center bits are needed or not for 2x2 Corner Wang tiles. It is needed, if you don't have them filled you will have a headache trying to figure out what's wrong.

From: https://docs.godotengine.org/en/latest/tutorials/2d/using_tilemaps.html

✓ Painting tiles with connect mode works well so thank you for your hard work on it, great job.

(2) UX issue. The path tool doesn't make much sense in the 2x2 corner wang mode - it throws a bunch of errors when painting with path mode.

Possible fix is just to hide the path icon when using 2x2 corner wang tiles, as 1x1 paths don't exist in corner wang tiles?

(3) Bug - eraser breaks auto-tiling.
Some examples: (Yellow arrow is where I clicked and what happened, bottom is expected behavior):

Steps to reproduce

Run the project provided and use the eraser on the tiles.

Why are center bits needed at all for 2x2 Wang tiles? If you were using 2x2 corner Wang tiles where the corners need to match, why not paint the corners directly?
