Currently if an artist wishes to do some icon theming they have to run some scripts when they save an image to re-pack (by zipping) their icon theme of interest, and then re-start LibreOffice. That is a bit of a pain. It would be lovely if the icon loading code could support a look-aside directory tree beside the icon-theme, and preferentially load from there if it is present. Currently we look in share/config/images.zip (for example). It would be wonderful to (one-off at startup) check if a share/config/images/ directory exists - and if so to resolve paths against this [ and also turn off icon caching so no re-load is necessary ]. The code is here, for image load: http://cgit.freedesktop.org/libreoffice/core/tree/vcl/source/gdi/impimagetree.cxx#n195 and cache: http://cgit.freedesktop.org/libreoffice/core/tree/vcl/source/gdi/impimagetree.cxx#n343 and to check if a directory exists we should use the sal/inc/osl/file.hxx code I think.
