 * pixelated`, non-integer downscales drop source pixels — bitmap-font glyphs
 * lose strokes and look "broken". `auto` lets the browser bilinear-filter
 * during the transform, which is consistent at any scale (very slightly
 * softer at 1:1 than nearest-neighbor would be, but the canvas internal
 * resolution is unchanged so no detail is lost).
