Gradient display-list commands currently carry a Vector<Gfx::ColorStop>, which keeps command payloads tied to an owning container. Split resolved gradient stops into parallel color and position arrays so the display list can later store those arrays as contiguous inline data. This keeps the painting behavior the same while removing another nested object shape that does not map cleanly to the flat command-buffer format
