Fix T45795, bevel treated one-edge-beveled case inconsistently.

When one edge is beveled at a vertex among more than 1 other unbeveled
edges, the code makes a polygon around the vertex. The position of the
vertices on the non-adjacent-to-beveled-edge edges depended on the
ordering of edges, which leads to inconsistent-looking results in seeming
symmetrical situations.  Changed to use the bevel amount as slide
distance, which fixes this.
