<title>Bug 1452337: sampling a sprite sheet cell must not pull in its neighbours</title>

<style>

html, body { margin: 0; background: white; }

/* The centre cell of the sheet is green and every neighbour is red, so any

   red pixel means filtering sampled outside the cell. The fractional zoom is

   what makes the sampling non-integer. */
