+Note: Sprite images have to be loaded. This is done asynchronously, meaning a sprite might not appear on the canvas after the first call to `drawSprite`.
+
+Note: The sprite images are cached internally on it's `name`, `width` and `height` property. If these are values are different between calls, new sprite images will be loaded. This means that after a resize, the sprite may not appear immediately.

+### `drawSpriteRotated`
+
+```ts
+lib.drawSpriteRotated(x: number, y: number, width: number, height: number, name: string, angle: number) -> void
+```
+
+Same as `drawSprite`, but the sprite is rotate according to the `angle` parameter, specified in radians (meaning a full rotation is `2 * Math.PI`.) The sprite is rotated around the **center**.
+
+Note: Angles have a granularity/precision of 360 steps per rotation. This is becuse sprite images are cached internally on `angle` in addition to `name`, `width` and `height`.
