I've done it on Ubuntu, but the list of dependencies is horrible. SDL introduces PulseAudio and whatnot. My next guess would be to use Debian ...

In Ubuntu, for example, you can use Super-M to invert the screen colors (requires desktop effects, see [1]). Other OSes have similar abilities, although I'm not really concerned with anything other than Linux.

Hello, I've got a bug with UTF-8 normalizations: as far as I understood, there's (at least) two ways to write an 'é' in UTF-8 : CC 81 and C3 A9.
