Function AddVertToAllEdges

editor/HRoom.cpp:886–897

Adds a new vertex to all instances of a given edge

// Adds a new vertex to all instances of a given edge
void AddVertToAllEdges(room *rp, int v0, int v1, int new_v) {
  face *fp;
  int f, v;

  for (f = 0, fp = rp->faces; f < rp->num_faces; f++, fp++) {
    for (v = 0; v < fp->num_verts; v++) {

    }

// Adds a new point to all instances of a given edge
// First adds the point to the room (or finds it there), then calls AddVertToAllEdges()
