Class PlatformerGraphDrawer

Makes it extremely easy to 'draw' a platformer graph. Just add lines/edges and close enough vertices will automatically be joined together.

Syntax
public class PlatformerGraphDrawer
Examples
void Example()
{
    // create a drawer which merges vertices that are closer than .1f
    var drawer = new PlatformerGraphDrawer(.1f);

    // draw a square
    drawer.AddUndirected(new float2(0, 0), new float2(1, 0));
    drawer.AddUndirected(new float2(1, 0), new float2(1, 1));
    drawer.AddUndirected(new float2(1, 1), new float2(0, 1));
    drawer.AddUndirected(new float2(0, 1), new float2(0, 0));

    // create our graph
    var graph = new PlatformerGraph(Allocator.Persistent);

    // populate it with our square
    graph.Populate(drawer.Vertices, drawer.UndirectedEdges);
}
