Actually I believe it's all stored as an array.
I'm not sure why hotspots are 2x2 pixels, probably because it's not as important to have 100% pixel perfect placement for a hotspot, and there's also no point in beefing up a games size just for that.
But the walkpaths I know are 2x2 mostly because of the path finding algorithm having twice as much to calculate if it were single pixels.
