Hello! It's my first time engaging with the Godot Community (I'm a lurker)!
Given a triangle face from MeshDataTool with 3 vertices [v0, v1, v2] and 3 edges [e0, e1, e2], how many edges should each vertex have, and which ones?
EX: Should the vertices edges be v0[e0, e1], v1[e0, e2], v2[e1, e2]?
Context: Need to confirm if this PR corrects the issue of some of MeshDataTool's vertices having only one edge by checking if the PR gives the expected behavior. There are also other issues in MeshDataTool i want to address once I understand this part.
