* \brief This class can be used to draw a single path on an image.
*
* It encapsulates the use of the otb::DrawPathListFilter by internally creating
* an otb::ObjectList<TInputPath> of size one and passing it to a DrawPathListFilter.
*
* Please note that iterating this filter to draw several path is NOT efficient. If you
* have several path to draw, consider using the otb::DrawPathListFilter.
