Decoding a placed raster built a second full-size pixel vector from the
RGBA image and premultiplied every pixel into it. The pixels are now
premultiplied in place, opaque pixels are skipped, and the buffer becomes
the pixmap's pixels without a copy (bytemuck's cast_vec, with a copy when
the capacity is not a whole number of pixels). The rendered SVG path
reuses its buffer the same way. For a 6000 x 4000 opaque image the step
takes 7 ms instead of 120 ms, with identical pixels.
