I have started rebasing my patches on top of the new geometry - it is a bit different of how I implemented it, but I'll take care of it. I'll review as I go - some of the changes I have might make sense to squash in your patches to keep a clean history... I'll add a couple of patches abstracting the geometry so that at core.c level we only work with a single geometry structure. This is they way it is done in the early patches I pointe you to before. Then it is patches building bottom-up support for the new features in 2.0. Javier
