But won't it be a problem for building dynamically loadable modules? The sword25 plugin would have to be linked against libpng explicitly, which could be impossible for e.g. Windows and WinCE (if I understand correctly, please correct me if I am wrong).

Hence, we still may have to provide a png loader wrapper in graphics/ to fully support those. Of course as always in a way that minimizes impact on small devices that don't want this (i.e. we'd only build png support in it libpng is detected, and only if sword25 is built, or dynamic plugins support is enabled).
