/**
* This package contains general math utilities used by `js-draw`.
* These include 2D and 3D vectors, 2D paths, and 3x3 matrices.
*
* ```ts,runnable,console
* import { Vec2, Mat33, Rect2 } from '@js-draw/math';
*
* // Example: Rotate a vector 90 degrees about the z-axis
* const rotate90Degrees = Mat33.zRotation(Math.PI/2); // π/2 radians = 90 deg
* const moveUp = Mat33.translation(Vec2.of(1, 0));
* const moveUpThenRotate = rotate90Degrees.rightMul(moveUp);
* console.log(moveUpThenRotate.transformVec2(Vec2.of(1, 2)));
*
* // Example: Bounding box of some points
* console.log(Rect2.bboxOf([
* Vec2.of(1, 2), Vec2.of(3, 4), Vec2.of(-100, 1000),
* ]));
* ```
