ROUND will deproject an image by assuming that the true shape of the object is a circle projected into an ellipse of a given position angle, ellipticity (1-b/a) and center. Creates a new image in the `dest' buffer from the original image in the `source' buffer.
The SINC keyword instructs ROUND to use high-accuracy sinc interpolation instead of the default bilinear interpolation algorithm.
The NORM keyword is used to renormalize the pixel intensities (surface brightness/pixel) in the transformed image.
