Create a Gabor Kernel in a neighborhood definition

Parameters:

	nhb	: a pointer to FLGR_Data1D
	lambda	: wavelength of the cosine factor of the gabor funtion
	theta	: orientation of the normal parallel stripes of the gabor function (rad)
	phi	: phase offset of the cosine factor of the gabor function (rad)
	gamma	: ellipticity of the gabor factor (generally 0.2 < gamma < 1)
	bandwidth	: spatial frequency bandwidth of the filter (generally 0.4 < bdwdth < 2.5)
	offset	: offset to apply to gabor function (apply before amplitude)
	amplitude	: amplitude to apply to gabor function

Returns:

FLGR_RET_OK, ...
