Qimage: new "pyramid" interpolation

This is a followup to the rather lengthy discussion regarding the "interpolation tests" poll that can be found here:

Of the dozen or so people who answered the poll, it appeared that Qimage's vector interpolation and Genuine Fractals were the preferred methods, with the preference between the two changing depending on the image used. I've been working on a new interpolation method that I call "pyramid" interpolation which is better than vector, especially for very large stretches of the original. The new pyramid interpolation is now available in Qimage v2004.130.

I've taken the liberty of adding the pyramid results to the initial samples posted. The results can be found below. In the case of the bug sample, I only included the Genuine Fractals and vector results since those were preferred from the samples given.
