Peter Keresztes Schmidt 29488900a1 Box: Make range calculations mathematically correct 2021-05-16 19:41:45 +02:00
Peter Keresztes Schmidt 3c85d63655 Polygon: Implement clipping to a boundary box
Using the Sutherland-Hodgman algorithms convex and concave subject polygons can be clipped
by convex clip polygons.
For now we only need clipping to rectangles (Box), so limit our implementation to that. If needed this can be
trivially extended to convex clip polygons (a check whether the clip polygon is actually convex has to be added).
If convex clip polygons are needed we have to switch to e.g the Vatti algorithm.

Peter Keresztes Schmidt e6c159fb70 Vector2: Make coordinate components public
The components were already unconditionally/without side-effects writable. Let's make them public so we don't need the setters.

Peter Keresztes Schmidt 290b88e5ac Vector2: Delete non-idiomatic comparison operators
The "greater than" and "lesser than" operator families don't make sense for coordinates.
If lexicographic comparison for ordering purposes is needed, it should be implemented separately.

Peter Keresztes Schmidt 60db1c2eaf Coord: Rename to Vector2
The class is not only used to represent coordinates but also lengths in XY.
Vector2 is a more fitting/general name for this purpose.
