  * @property {boolean} [antialias=true] - When set to `true`, WebGL uses linear interpolation to draw scaled or rotated textures, giving a smooth appearance. When set to `false`, WebGL uses nearest-neighbor interpolation, giving a crisper appearance. `false` also disables antialiasing of the game canvas itself, if the browser supports it, when the game canvas is scaled.

  * @property {boolean} [pixelArt=false] - Sets `antialias` and `roundPixels` to true. This is the best setting for pixel-art games.
