Research direction
Start by locating the multi-layer compositing implementation and any existing image-processing tests. Compare its handling of alpha PNG output, alpha-channel loading, and layer compositing against the three goals in the issue; done means non-alpha images avoid alpha work, compositing can exit for fully opaque pixels, and output uses alpha PNGs only when needed.
Written by the indexing model from the issue text.
Description
- only send out alpha pngs when at least one of the layers has an alpha channel
- don't load alpha channels for non-alpha images
- composite all layers at once and early exit when pixel is fully opaque
