transform

K.transform(a: number, b: number, c: number, d: number, e: number, f: number): void

Multiplies the current transform by a 2D affine matrix. This is the native Canvas 2D method.

[a  c  e]
[b  d  f]
[0  0  1]

// Translate by (100, 50)
K.transform(1, 0, 0, 1, 100, 50);

// Uniform 2× scale
K.transform(2, 0, 0, 2, 0, 0);

// Rotate 45 degrees
const angle = Math.PI / 4;
K.transform(
  Math.cos(angle),
  Math.sin(angle),
  -Math.sin(angle),
  Math.cos(angle),
  0,
  0,
);

Transforms accumulate. Use K.push() and K.pop() to isolate custom matrices.

To replace rather than multiply the current transform, use native K.setTransform(). Remember that Klint's base transform includes DPR and possibly a centered origin, so replacing it directly also replaces those conventions. Prefer push()/pop() for normal sketch transforms.
