Hi! To fulfill this comment in lout/debug.hh: /* * Following is experimental, and will be explained soon. */ See <http://www.dillo.org/~sgeerken/rtfl/> for a short description and a tarball to dowload. This is a re-implementation of a prototype I wrote several years ago, which then proved already very useful for debugging subtleties of "incremental resizing", but was unfortunately lost. I hope that the new version will be equally useful for debugging floats. RTFL is not restricted to dillo, so feel free to use it in other projects. Sebastian
