Seam Carving

I've just come across this awesome technique:

One of the reasons designers like to use fixed rather than fluid website layouts is because of the difficulty in providing attractive images at unknown aspect ratios. This technique offers a really beautiful solution.

The presentation shows that all that is needed to apply the effect is an image plane containing the priority of each pixel or effectively in which seam removal it is to be eliminated.

I demand that:

  1. There be a PNG extension chunk defined to encode this plane.
  2. Web browsers support this new chunk when non-proportionally scaling images.
