Edit Mode Selection: Make Vertices not occluded by edges

Debugging the edit mode selection I realized the vertices are often
occluded by edges with the same depth. Sometime it can be the center
pixel of a vertex point and that can lead to some selection issue.

So I increased the offset a bit for the vertices and it seems to fix it.
