Comment (by azaozz):

 In 48472.diff:
 - Run the `wp_generate_attachment_metadata` filter at the end in
 `wp_update_image_subsizes()` when new metadata was generated and
 additional image sub-sizes were created. This ensures consistent behavior
 with earlier WP versions.
 - Add pass another arg in the `wp_generate_attachment_metadata` filter to
 add context.
 - Fix some inline docs and ensure the new image meta is always saved
 before starting post-processing.
