class MvtSpriteEntry(val name: String, val x: Int, val y: Int, val width: Int, val height: Int, val pixelRatio: Double = 1.0, val content: IntArray? = null, val sdf: Boolean = false)
One icon's slice within a Mapbox-format sprite sheet: pixel rectangle within the atlas PNG plus optional pixelRatio (@2x / @3x HiDPI variants ship the same icon at integer scales of the base; the renderer divides by pixelRatio when sizing the on-screen Placemark).
