IMG_SHIFTED = SHIFTIMAGE(IMG, FRAC_DELTAX, FRAC_DELTAY);

Shifts the image IMG using the Fourier shift theorem by the Field-of-view (FOV) fractions FRAC_DELTAX and FRAC_DELTAY.

The fraction is relative to the size of the image such that a value of 1.0 shifts the image back to where it started. Shift fractions outside this range will wrap around to the corresponding shift within the range.

The shift is performed using Fourier sinc interpolation, i.e. the Fourier shift theorem, via simple phase adjustments in the frequency domain. This may lead to Gibbs phenomena.
