@ -96,8 +96,8 @@ corners; the centre of a pixel addressed as (0, 0) actually lies at (0.5, 0.5).
Coordinates are usually passed to the library as 2-tuples (x, y). Rectangles
are represented as 4-tuples, with the upper left corner given first. For
example, a rectangle covering all of an 800x600 pixel image is written as (0,
0, 800, 600).
example, a rectangle covering all of a 2x2 pixel image is written as (0, 0, 1,
1).
