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.)
Implement traffic in MapStructure and use it. Various other hacks and/or
cleanup. Feedback required on whether this is a lot better than before.
Also partially revert 9c018d94c4d88dad7476ec250fa3b52024526f4b to add
feature to geo.PositionedSearch: it me._equals is overridden then the
old mechanism is used instead of the new C++ function, so that the
custom equality can be used. (In particular for the Fixes with the
TrafficModel class).
In time for 3.0. The API is still not fully complete, and not fully
cleaned up, but this is good enough for this release cycle (and it
should offer benefit longer term, if not now -- hopefully performance as
well).
Many thanks to Hooray as well, who has helped prepare things while I
could not, and often suggested ideas.
