Mercurial imgtrack extension

Programmers have been using version control systems for decades to record/log/merge/revert changes in their source code. Photographers don't have a similar tool, although they also have to wrangle with many different versions of one photo:

1. a photo is typically shot in a Camera RAW format, a kind of digital negative, that needs automatic or manual processing to produce a visible image on the screen
2. the edited Camera RAW photo has to be saved in another format (e.g. Photoshop PSD or JPEG), because RAW is basically a read-only format. Often multiple versions of one image are saved to test different effects and filters.
3. then the edited photos are published on photosharing sites or online photo galleries. To increase the upload speed, optimized JPEG versions of the source files are created. The gallery software might create additional versions of the image (e.g. thumbnails and smaller previews).

The problem

This multifile-workflow brings a few problems:

OxJs - jQuery for your Bytes

OxJs (speak: HexaJs) is a utility library for javascript, that facilitates parsing and creation of binary data in Javascript. While this sounds weird in the first moment, there are a few areas where OxJs can come in handy:

• If you need to transfer huge amounts of numercial data via AJAX, binary encoding can be much more space-efficient than transfering it in JSON. The number 41239 for example needs 5 Bytes in JSON, but only 2 Bytes in binary encoding (unsigned short). A more practical example is the The Google Maps Polyline Utility, which saves over 80% of the json payload by binary encoding. However, de- and encoding binary information can be a quite tricky and this is were OxJs helps.

• For client-side file parsing: Recent enhancements in Javascript allow us byte access for to-be-uploaded files. This can be used to perform enhanced sanity che
