1.6
	- Fixed displayed values of D30's C.Fn 2 (based on the values
	  displayed in the menu of an actual (although pre-production)
	  camera.
	- Added anchors to index pages so that links from images go to
	  the right area of the page.
	- ingest now ignores the hidden flag on DOS files.
	- Change circle of confusion to be 1.4142 pixels.
	- Fix a few places were the generated HTML wasn't XHTML-compliant.
	- Don't be messy if a camera doesn't report ImageWidth or
	  ImageHeight (e.g. Kodak DC215).
	- Remove digital zoom from focal length when calculating DOF.
	  The Nikon CoolPix cameras report a scaled-up focal length.
	  Not yet sure if this is Nikon-specific behaviour.

1.5
	- Fixed Nikon handling to not be dependent on model name.
	- Rewrote ingest's filename mapping (having now read the DCF spec).
	  Also rewrote directory pruning code - currently passes all tests.
	- Nikon "converter" tag is set for all converters, not just fisheye.
	- Use exposure bias in EV calculation.
	- Attempt to calculate & report depth-of-field when we have enough data.
	  This feature is still experimental.  It currently assumes a circle of
	  confusion of one pixel.
	- Decode and display EOS D30's Custom Function data!
	- Use CompressedBitsPerPixel tag to decode if D30's in Fine or
	  Normal mode.  This is probably hidden in MakerNote data, but
	  we havent' decoded that yet.
	- Slight updates having read the EXIF 2.1 standard.
	- Display camera's firware revision.
	- Gather and report MaxAperture tag (widest aperture supported by
	  the lens).  While this successfully hints (when combined with the
	  focal length) at which lens was used on the EOS D30 SLR, some
	  cameras sometimes give values narrower than the photo's aperture
	  (e.g. Kodak 290, Nikon 880, Epson 850).

1.4
	- Handle multi-part TIFF files (such as those from the S1Pro).
	- Extended ingest's handling of DOS pathnames.  Cleaned up
	  directory pruning.
	- Only report Casio digital zoom if not 1x.
	- Add extended handling for Nikon 880.
	- Parse orientation tag.

1.3
	- Ensure that corrupt images are cleaned up if calls to
	  ImageMagick fail (the most common point for ^C to happen).

	- ingest no longer preserves DOS mtime.  It's rarely the same
	  as the Unix time (clock skew as well as timezone issues) and
	  the image time should be in the EXIF data anyway.

	- Reduced default height of "SVGA" images slightly.

1.2
	- Added ingest to quickly read files from camera cards.

	- Fixed newimagedir so that web/web is not created on second
	  execution.

	- Stopped using "-sharpen" when generating JPEGs.
	  It was having a fairly nasty aliasing effect on some images
	  (especially SuperCCD images).
	  Better solution will be to use UnSharp Mask (in The Gimp).
