/** \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
