#58155 new enhancement
Add filter to allow large image scaling of PNGs

Description
Due to Issue #48736,large image downscaling of PNGs is disabled because sometimes the new images are larger in filesize than the originals (particularly with PNG-8).
This is reasonable but should be filterable with the current state as the default.
There are use cases where users rarely, if ever, upload PNG-8s but do upload massive PNG-24s that would benefit from downscaling. Devs should be able to turn this feature on for PNGs as needed.

Replying to costdev:
As this was introduced in 5.3.1, I'll update the
Version
property to note when this first became an issue.
Apologies for that. Still learning the system. We have a couple others potential issues to report so will hopefully do a better job.
It looks like we could change this condition:
to:
<?php if ( 'image/png' !== $imagesize['mime'] || apply_filters( 'big_image_scale_png', false, $imagesize, $file, $attachment_id ) ) {
That would do it from our perspective. Would love to see this and doesn't seem like there would be any downside.
