PolygonTrigger::ParsePolygonTriggersDataChunk rejects point shapes, but not line shapes

[xezon]

What is a line trigger good for? Does it do anything?

Bool PolygonTrigger::ParsePolygonTriggersDataChunk(DataChunkInput &file, DataChunkInfo *info, void *userData)
{
...
		if (numPoints<2) { // Why not < 3 ?
			DEBUG_LOG(("Deleting polygon trigger '%s' with %d points.",
					pTrig->getTriggerName().str(), numPoints));
			deleteInstance(pTrig);
			continue;
		}
