Texturepacker

========================

3 April 2011


- `Map.get_alt_list` allows `stone1` as well as `stone_1`, but knows
that `crop0`, ..., `crop7` are not alternative versions of a
nonexistent texture `crop`.

- Bug fix: using a string to fetch an atlas resulted in an infinite
loop! Now the string is instead treated as a URL

- Feature: map method `Map.get_alt_list` gets a list of candiates for
making an alternative-textures remix of a pack.

- Bug fix: Setting a cache directory with `set_http_cache` should now work!

====

- New recipe keywords `unjumble` and `if_missing` to work with ZIPs containing files with
the correct names but in the wrong folders.

- Bug fix: LazyPack returned wrong value for last-modified. Missing test :-(

9 March 2011

- New recipe keyword: `pack_icon`: create a `pack.png` from the terrain file.

- Add `get_last_modified` and `is_modified_since` methods to resources and
packs.

- Hence make the `maketexture` script avoid rebuilding packs if their
ingredients are unmodified.

- Support `../` and `./` when resolving partial references with custom URLs
as base URL per <http://tools.ietf.org/html/rfc3986>.
