Add Support for *.CR2, *.NEF and *.RAF File Extensions about lximage-qt

[tsujan]

I can open image/x-canon-cr2 with lximage-qt here.

lximage-qt opens all images supported by Qt. Probably, you don't have a complete Qt5 installation. Specifically, you need qt5-imageformats (or whatever name it has in your distro).

erm - veto :P - cr2 is not in the list of supported formats in qt5-image-formats-plugin

maybe some things are picked up from libraw, i read that they have an qt interface since some time.

Anyway, it isn't an lximage-qt problem.

Moreover, his lximage-qt installation is very old.

Re Image formats - we should just use what qt provide - dunno the specs of the several raw formats - but i know a very good application that will fit for these tasks better than our simple image viewer. It's called nomacs - and it is in debian. If one want the current version one should switch to buster. Right now i don't care about backports - i guess i will do with the upcoming stable.

Conclusion: We should not re-invent wheels - the nomacs guys build the nomacs image lounge exactly for big images and big collections if i understand them right. Maybe i misunderstand the usecases of nomacs, i'm only the maintainer :D
