optional Union Reference

Detailed Description

Given two vectors of non-overlapping rectangles defining two regions of the space: one mandatory region that must be occupied and one optional region that can be occupied, try to build a vector of as few non-overlapping rectangles as possible defining a region R that satisfy:

• R \subset (mandatory
• mandatory \subset R.

The function updates the vector of mandatory_rectangles with R and optional_rectangles with optional_rectangles \setdiff R. It returns true if the mandatory_rectangles was updated.

This function uses a greedy algorithm that merge rectangles that share an edge.
