 - GRAY, RGB, CMYK, YUV iterators with bit fields specified
 - SVG text tag, styles, def refs (e.g. text pathes, styles)
 - black / white- point

Array subscription, ala:
image[][]

type inside the image: RGB, YUV, CMYK, palette (direct, without expansion on load)

 - cheap copies
 - copy on write
 - sub-images
 - shear
 - rotate by double shear

Loaders:
 - palette saving
 - gzip / bzip2 / ... compressed streams
 - http:// et al (libcurl or so?)
 - 2 and 4 bit TIFF "imperfect"

General:
 - Exif, XMP and ordinary, classic comment support 

Algorithms:
 - rgb_A_ iterator and thus scaling, rotation
 - faster and ddt scaling!
 - descreen
 - blur
 - sharp, unsharp
 - all the others
 - affine transforms
 - 2D Baccode recognition: Datamatrix, Semacode, BeeTagg and QR 

Colorspaces:
 - more generic but faster and let all algorithms use it in the most generic form
 - RGBA
 - float, double support
 - CMYK
 - YUV
 - sRGB vs. Adobe RGB
 - ...

Frontends:
 - edentify:
   - more complete
 - econvert:
   - seperate channels
 - edisplay:
   - browsing
   - thumbnailing
   - slideshow
   - partial decoding on load
   - faster zooming
