psImageFFT doesn't recycle any psImage

[robert.desonia@…]

Most functions that returns a psImage takes a psImage parameter to recycle. The
FFT functions, however, do not. Is this just an oversite, or was that on purpose?

The same question applies to psVectorFFT, btw.

I suspect this was an oversight.

[robert.desonia@…]

I propose the following prototype changes:

psImage* psImageFFT(psImage* out, const psImage* in, int flags);
psImage* psImageReal(psImage *out, const psImage* in);
psImage* psImageImaginary(psImage *out, const psImage* in);
psImage* psImageComplex(psImage* out, psImage *real, const psImage *imag);
psImage* psImageConjugate(psImage *out, const psImage *in);
psImage* psImagePowerSpectrum(psImage* out, const psImage* in);

Fixed the image ones, and checked that this was mirrored for the vectors:

psVector *psVectorFFT(psVector *out, const psVector *in, psFFTFlags direction);
psVector *psVectorReal(psVector *out, const psVector *in);
psVector *psVectorImaginary(psVector *out, const psVector *in);
psVector *psVectorComplex(psVector *out, psVector *real, psVector *imag);
psVector *psVectorConjugate(psVector *out, const psVector *in);
psVector *psVectorPowerSpectrum(psVector *out, const psVector *in);
