asyncSweepLinestringToFacetsXYReturnChains MethodStatic

Find segments (within the linestring) which project to facets.

• This is done as a sequence of "await" steps.
• Each "await" step deals with approximately PolyfaceQuery.asyncWorkLimit pairings of "linestring edge" with "facet edge".
• PolyfaceQuery.setAsyncWorkLimit() to change work blocks from default.
• Return chains.
• Facets are ASSUMED to be convex and planar, and not overlap in the z direction.
