Better than the one we currently have. For now in rosapps, so we can test it, if it's all working fine, we should replace the wine one. Changes by me: use pow() instead of cbrt(), as cbrt doesn't work in our tree. I imported the whole codebase, although the mpfr files are not used. I moved the localizations to "lang" and the icons to "res" subfolder. svn path=/trunk/; revision=31512
