  1. Fix two bugs in Hash and Queue, respectively.

    The Hash control was attempting to use precision -Infinity for zoom level zero.
    Now it uses precision 0. The Queue's image method was not passing the loaded
    image to the callback function, unlike the other text, xml and json methods.
    Having the image available to the callback allows the implementation of post-
    processing with canvas, for example.

  3. Don't include HEAD revision in polymaps[.min].js.

    When these generated files were not part of the repository, it made sense to
    include the HEAD revision id, so that we knew how the files were built. These
    IDs are no longer needed as Semantic Versioning gives us the same information
    (and more!).
    Furthermore, now that the generated files are part of the repo, the HEAD
    revision would be the commit prior to the one that included the generated files,
    which is both confusing and causes spurious modifications if the files are
    rebuilt after pulling.
    Note: since this is a minor comment-only change, I'm not bumping the version.

  1. Rewrite world example.

    The world.json file now contains only country outlines, with a separate
    JavaScript data file. Quantiles are computed using Protovis with colors by
    Cynthia Brewer.

  3. Polymaps 2.0! (Or, proper support for tile size.)

    That was a SemVer joke, because this isn't a major new release in the
    vernacular sense, but there are some necessarily backwards-incompatible (and
    hence major) changes. The "major" changes are:
      `layer.size` replaced by `map.tileSize`.
      `layer.size(null)` replaced by `layer.tile(false)`.
      `map.pointCoordinate` no longer takes a `tileSize` argument.
      `map.coordinatePoint` no longer takes a `tileSize` argument.
      The tile projection no longer has a `coordinateLocation` method.
    The reason I could not make these changes as a patch version is that there was a
    fundamental misinterpretation of tile size (at sizes other than 256x256). In v1,
    Polymaps only supported tile sizes that were powers of 2, and larger tiles would
    cover a greater location area; for example, a 512x512 tile would cover Earth at
    zoom level 1. In v2, the size of tiles does not affect the mapping between
    locations and coordinates. So, there is always one tile that covers Earth at
    zoom level 0, 4 at zoom level 1, and so on.
    Thus, Polymaps now supports arbitrary tile sizes. Furthermore, the tile size is
    defined on the map object, rather than the layer, because the tile size affects
    the mapping between coordinates and points and should ideally be consistent
    across layers. (However, if it's not, you can always scale the tiles up or down
    to fit.)
    Now that the tile size does not affect the conversion between locations and
    coordinates, the `coordinateLocation` and `locationCoordinate` methods no longer
    take a `tileSize` argument. The `map` class now also has "static"
    `coordinateLocation` and `locationCoordinate` methods. The `locationCoordinate`
    method returns a coordinate at zoom level 0 (unlike the instance method, which
    returns a coordinate at the map's zoom level). You can use these methods in lieu
    of the old `coordinateLocation` method that was part of the tile projection
    (the second argument to the layer's `load` function).
    The reinterpretation of tile sizes changes how "world-size tiles" are
    implemented for GeoJSON layers with hard-coded features. Now you can disable
    tiling on a layer by calling `tile(false)`, which is demonstrably more obvious
    than `size(null)`. Better yet, the new implementation of non-tiled layers fixes
    the buggy behavior of v1, which had a difficult time crossing zoom level 8 and
    dealing with zoom transforms on top of world-size tiles. Rejoice!
    A few additional goodies in this commit:
    The `geoJson` layer now supports an optional `fetch` function to the
    constructor. This function is called to load the GeoJSON data and takes two
    arguments: a string containing the URL to load, and a callback function to
    invoke once the GeoJSON data is available. This feature allows you to write a
    GeoJSON transcoder from other formats!
    As an example of GeoJSON transcoding, see the new "kml" example. It loads a KML
    file and converts it to GeoJSON, and then gets displayed as a layer. KML support
    is still experimental (and only very rudimentarily supported, at the moment), so
    for now KML support lives in the examples directory. Depending on demand we will
    probably implement more support for KML and make it part of the official
    The `queue` class now supports fetching XML (as needed to support KML).
    Lastly, there's a new "world" example which shows a nice choropleth world map
    using a non-tiled layer. It would certainly be nice to have multi-resolution
    GeoJSON tiles for world country boundaries, but this sufficies for a simple
    world map!

  9. Fix bug in clipping in WebKit nightlies.

    The clipPath needs to be earlier in the DOM than any elements that reference the
    clipPath. Therefore, insert the clipPath at the beginning of the layer container
    rather than at the end.
