Description
Write a variant of the image warping functions that uses the new lsst::afw::geom::SkyWcs class. Compare performance with the old warper. It seems very likely we'll need to vectorize the transforms (of pixel position on the destination image to pixel position on the source) to get good performance, but confirm this.
Is it worth also experimenting with the AST internal warp codes?
