Distance = 0.

There are two or more boxes drawn inside the toplevel and sharing boundaries with toplevel.

A path is something you obtain by somehow drawing from one point to another, e.g. a line, and then starting another drawing between two points from the end point.

A dotted line is a generalized line that cycles between a color pattern, e.g.:would be a line:An extra color "transparent" may also be added to not change for that pixel.

A rectangular container.

The toplevel viewport is always implicitly understood as a special box.

Rectangle is like a box but always fully filled.

There is no unique solution, we just have to optimize something, often the least changed colors.

An "object" is a set of points that is understood to be one singular entity.

Contiguity and having the same color are strong indicators that something should be understood as an object.

If a color is inferred to be a background color, it contains no information and should be ignored.

Most problems tend to use black as a background color, but not all of them.
