This isn't just a "cute" feature: image meta-data can also be useful for post-rendering processing, e.g. `snogbloom` could automatically determine the correct image field of view using sensor-size and focal-length meta-data.

Simple EXIF support is added by exif-20061030-1.patch, but probably it's better to use a more general abstraction (e.g., just keep meta-data in a `ValTable` until output time), so that other meta-data formats like XMP and IPTC can be supported.
