Fix the main bugs, add features and convert most of the layers. Move/refactor some things as well. Add a canvas map dialog next to the built-in one -- it's not 100% functional but it's quite close actually. As before, the excitement has been taking place at our team clone. https://gitorious.org/fg/canvas-hackers-fgdata/commits/0b4cc84 (topics/canvas-map-dialog branch this time, current HEAD in above URL.)
