Get shapes that are colliding with ``shape`` and the vector to separate the shapes. Get shapes that are colliding with ``shape`` and the vector to separate the shapes.
The separating vector points away from ``shape``. The separating vector points in the direction that ``shape`` has to move to clear
the collission.
The length of the vector is the minimal amount that either shape has to move to
clear the collission.
The table is a *set*, meaning that the shapes are stored in *keys* of the table. The table is a *set*, meaning that the shapes are stored in *keys* of the table.
