Bug#987063: gwenview: looses image metadata on jpg rotation

[Karsten Hilbert <karsten.hilbert@gmx.net>]

Package: gwenview
Version: 4:20.12.3-1
Severity: normal
Tags: upstream

This release started to drop metadata from JPEG files after rotating
them. I do believe the following upstream commit is the culprit:

	https://invent.kde.org/graphics/gwenview/commit/a401e66621bcffbdc75048d9eaded1a5f5a67137

because it "unconditionally" saves JPEGs thereby overwriting them w/o
carrying over metadata :(

Thanks,
Karsten
