I guess we now have Sprite Animations

The author added animated sprites to their wgpu-based engine by loading a spritesheet and slicing it into sprites.

Each sprite stores UV coordinates that map to its region on the spritesheet and are used by the renderer.

A SpriteAnimator controls which sprite to show and when, while the SpriteRenderer draws a 2D quad with the sprite's UVs.

The author also implemented text rendering, demonstrated by an FPS counter in the demo.
