Image editor: make compressor work after the image editor, too

[lakesare]

Fixes #4903

BEFORE

With compressor
initial: 48kb
after compressor: 28kb

With compressor after editor
initial: 48kb
after editor: 43kb
after compressor: 43kb

AFTER

With compressor
initial: 48kb
after compressor: 28kb

With compressor after editor
initial: 48kb
after editor: 43kb
after compressor: 36kb - THIS CHANGED

Note that compressor doesn't compress the file as much after the editor - this happens because the editor already compresses the image in its own way.
