ImageStitchnow supports stitching images onto spherical and cylindrical canvases. Functions likeDefinitionandClearthat operate on symbols now consistently handle lists and string patterns. FindShortestTourhas a direct way to return individual features of the result, rather than always packaging them togethe...
