The renderer composited in 8-bit integers, so where a partly transparent anti-aliased edge crossed opaque art (or a background colour) the result came out at alpha 254 on some pixels, and PNG, TIFF and WebP files were written with an alpha channel. Raster exports (and Save for Web) now composite in floating point (vello_cpu's f32 pipeline, enabled as a feature), offscreen groups, masks and patterns included; the canvas keeps the faster 8-bit path.
