Tiling
data class Tiling(val matrix: Matrix, val extGState: ExtGState?, val paintType: Int, val tilingType: Int, val bbox: Rectangle, val xStep: Double, val yStep: Double, val contentBytes: ByteArray, val resources: PdfDictionary? = null, val baseColor: RgbColor = RgbColor(0.5, 0.5, 0.5)) : KitePattern
Tiling pattern (PatternType = 1). The content stream lives in contentBytes; the PDF renderer replays it once per tile across the filled region. baseColor is the flat approximation for consumers that don't replay cells (and the emergency fallback for degenerate cell geometry).
