Is is possible to use custom-size scaling with IIPImage?

Currently the backing images are served from IIPImage using pyramidal TIFF or JPEG2000 files. They are accessed through the DeepZoom protocol, which sends requests that matches the different pyramid levels. This has the side-effect of many pages requiring a lot of padding.

Switching to a scheme where all images are scaled to maximum available size inside of the source rectangle (currently 2_256 x 3_256 pixels) would ensure a better mosaic effect. The question is how well IIPImage handles odd-size requests.
