Int52_12 is a signed 52.12 fixed-point number.
The integer part ranges from -2251799813685248 to 2251799813685247,
inclusive. The fractional part has 12 bits of precision.
For example, the number one-and-a-quarter is Int52_12(1<<12 + 1<<10). Ceil returns the least integer value greater than or equal to x.
Its return type is int, not Int52_12. Floor returns the greatest integer value less than or equal to x.
Its return type is int, not Int52_12. Mul returns x*y in 52.12 fixed-point arithmetic. Round returns the nearest integer value to x. Ties are rounded up.
Its return type is int, not Int52_12. String returns a human-readable representation of a 52.12 fixed-point
number.
For example, the number one-and-a-quarter becomes "1:1024".

Rectangle26_6 is a 26.6 fixed-point coordinate rectangle. The Min bound is
inclusive and the Max bound is exclusive. It is well-formed if Min.X <=
Max.X and likewise for Y.
It is analogous to the image.Rectangle type in the standard library.MaxPoint26_6MinPoint26_6 Add returns the rectangle r translated by p. Empty returns whether the rectangle contains no points. In returns whether every point in r is in s. Intersect returns the largest rectangle contained by both r and s. If the
two rectangles do not overlap then the zero rectangle will be returned. Sub returns the rectangle r translated by -p. Union returns the smallest rectangle that contains both r and s.

Package-Level Functions (total 3)
I returns the integer value i as an Int26_6.
For example, passing the integer value 2 yields Int26_6(128).
P returns the integer values x and y as a Point26_6.
For example, passing the integer values (2, -3) yields Point26_6{128, -192}.
R returns the integer values minX, minY, maxX, maxY as a Rectangle26_6.
For example, passing the integer values (0, 1, 2, 3) yields
Rectangle26_6{Point26_6{0, 64}, Point26_6{128, 192}}.
Like the image.Rect function in the standard library, the returned rectangle
has minimum and maximum coordinates swapped if necessary so that it is
well-formed.
