bool ExpandSelectionByBoundaryLoops
(
FGroupTopologySelection & Selection
)
Remarks
Using the edges in the given selection as starting points, add any "boundary loops" containing the edges. A boundary loop is just the sequence of edges that surrounds a hole in the mesh, or the outside of an open mesh. The loop may not complete if it hits a bowtie vertex (a vertex with more than two incident boundary edges). true if selection was modified (i.e., were the already selected edges part of any boundary loops whose member edges were not yet all selected).
