The decoded-frame Skia image cache is useful for display-list rasterization because decoded image resources can be replayed over many frames. The cache lets that path reuse SkImage wrappers and GPU-backed copies instead of rebuilding them whenever the same resource is painted. For canvas, commands are consumed into one backing surface and decoded frames are already held by the command or paint style for the draw. A per-painter cache does not match that usage model, and can keep decoded frames and Skia images alive after the draw has consumed them. This removes the cache from PainterSkia and drops the now-unused pruning hook from CanvasCommandPlayer. With the cache gone, PainterSkia can hold its painting surface directly instead of allocating a private Impl. DisplayListPlayerSkia keeps owning the cache, so display-list rasterization keeps the SkImage reuse behavior.
