[Kde-imaging] QtRaw, a Qt image plugin using libraw

[Aurélien Gâteau]

Hi,

I was recently pointed out to https://github.com/mardy/qtraw . A Qt image 
plugin which uses libraw to load raw files. I contributed a bit to it, and I 
am now able to load .arw images with Gwenview.

The main thing missing is that right now the .desktop file lists only one 
mimetype: image/x-sony-arw. I know very little about raw files, so I don't 
know what would make sense to add there. Can you help?

More on file formats: the plugin announces itself as supporting the following 
formats:  cr2, arw, nef, raf and dng. The list is hardcoded in 
RawPlugin::keys(). Is there something smarter to do there (like getting such a 
list from libraw)?

The plugin also does something weird in RawPlugin::capabilities(), adding tif 
format there. I am not sure this is a good idea.

Anyway, your feedback on this is welcome. It would be nice if we can get 
distributions to ship this plugin, but before pushing distros to package it, I 
want to make sure it does not interfer with existing raw support in digiKam 
and other imaging applications.
