694cc05024 Fix polygon merging. Add polygon:scale(s, cx, cy).
Polygon merging failed due to invalid computation of shared edge.

polygon:scale(s,cx,cy) scales polygon by factor s wrt point cx,cy.

c681391033 Fix triangulation. Use class-commons. Add hash:draw()
Polygon triangulation bug:
In some cases Kongs triangulation algorithm produces triangles
with collinear points. The Polygon constructor removes one of
these and throws an error because there are not enough vertices.
Checking if the current points in a triangulation step are
collinear and discarding those triangles fixes the problem.

Class-commons lets you use any supporting class system as
backend for HC.

Add SpatialHash:draw() for debug purposes.
