IntSquareLike

X coordinate of the square's center

Y coordinate of the square's center

The extent is the half side length of the square

The bottom is defined as the center y coordinate plus the extent minus one, it thus designed the 'last pixel' still inside the square. This was changed from the previous definition of 'cy + extent' to be able to use the full 31 bit signed int space for a square without resorting to long conversion.

Checks whether a given square is fully contained in this square. This is also the case if their bounds full match.

Determines the quadrant index of another internal square aq.

Determines the quadrant index of a point a.

Calculates the maximum distance to a point in the euclidean metric. This calls maxDistanceSq and then takes the square root.

Calculates the maximum squared distance to a point in the euclidean metric. This is the distance (squared) to the corner which is the furthest from the point, no matter if it lies within the square or not.

Calculates the minimum distance to a point in the euclidean metric. This calls minDistanceSq and then takes the square root.

The squared (euclidean) distance of the closest of the square's corners or sides to the point, if the point is outside the square, or zero, if the point is contained

The right is defined as the center x coordinate plus the extent minus one, it thus designed the 'last pixel' still inside the square. This was changed from the previous definition of 'cx + extent' to be able to use the full 31 bit signed int space for a square without resorting to long conversion.

The side length is two times the extent. Note that this may overflow if the extent is greater than 0x3FFFFFFF.

The top is center-y minus the extent.

Note therefore, that the vertical coordinates are considered top-down as in screen coordinates, not bottom-up!
