/** \class GaborImageSource
 * \brief Generate an n-dimensional image of a Gabor filter.
 *
 * GaborImageSource generates an image of either the real
 * (i.e. symmetric) or complex (i.e. antisymmetric) part
 * of the Gabor filter with the orientation directed along
 * the x-axis.  The GaborKernelFunction is used to evaluate
 * the contribution along the x-axis whereas a non-normalized
 * 1-D Gaussian envelope provides the contribution in each of
 * the remaining N dimensions.  Orientation can be manipulated
 * via the Transform classes of the toolkit.
 *
 * The output image may be of any dimension.
 *
 * This implementation was contributed as a paper to the Insight Journal
 * http://hdl.handle.net/1926/500
