Rasterize

When true, the watermark is flattened to a raster image baked into every page instead of injected as selectable text/vector content, so it can't be removed by selecting/deleting text in a PDF editor. Trade-offs: larger output, no selectable watermark text, slight pixelation at deep zoom. Tamper-resistance, not DRM. Ignored when post-processing is skipped (watermarks require pikepdf). Default false.
