SUMMARY
Gwenview, Dolphin, SDDM, Lock Screen, Wallpaper are affected by missing support of jp2 (jpeg2000) support

STEPS TO REPRODUCE
1. Use "opj_compress" or:
2. Use "gm convert inputphoto.png outputphoto.jp2"


OBSERVED RESULT
1. Gwenview missing thumbnail of jp2
2. Gwenview missing support to display jp2
3. No wallpeper if jp2
4. Borken SSDM and lock screen,
5. Documents from Library of Congress are useless (jp2 is among ISO standards for archiving, hence photos in LoC are in .jp2)
6. Gimp can display and edit both jp2 photos (opj_compress and gm convert).

EXPECTED RESULT
Fix support for jp2 in KDE in general.
