Demo features : a keyboard / touchscreen-controllable spritesheet character that uses the pixel-accurate (and slightly
heavier) collision detection-variant (see API docs) to resolve collisions with the environment.
Viewport: on mobile screens (or resize your window to a portrait oriented view), the content of the canvas will be clipped by a Viewport
where the Viewport will center around the player character. The size of the canvas remains static as it describes
the "world" size, while the Viewport describes the visible area.
