Edit Mesh Overlay Geometry Shader: Ignore correction geometry for loops that are not part of an edge.

Browse Source 
By the tests I could only observe a considerable difference in the peformanse when the vertex size is 30.
Vertice 3 showed no difference in a suzzane with subdivision modifier level 3 + show-on-cage.

Point Size 30: 7.29ms vs 2.55ms
