Better icon names/ easier icon themes (fdo#30425)

I'm thinking (again) on work on this request.

Looking at the code, I got that icons for UNO commands are derived by
prepending "lc_" or "sc_" to the command name (with lower case).

So, if someone think it's good enough to reuse an icon (like a "Next"
arrow), it will duplicate images files, am I right?

Shouldn't the icon theme decides what image it's used to each thing?
An xml file could bind them (image name -> uno command name). And
then, internally keep (yeckt) using hrc/src files to binding them to
numeric ids.

Any thoughts? Or should I just rename the images (and their references
in hrc/src files)?

P.S.: I remember I saw a wiki page about this issue, but I can't find
it. Does anyone know where is it?
