Employ image classification to make better decisions about lossy conversion #883
Description
PNG files that are not photos will be lossy-converted to jpeg with
convert_png_to_jpeg enabled (which is in core). This noticeably degrades
quality.
Conversely, with convert_png_to_jpeg, convert_jpeg_to_webp, and
convert_webp_lossless, PNG files that *are* photos will be converted to webp
lossless. This leaves a lot of bandwidth-reduction on the table.
