Merge pull request #12827 from hrnr:stitching_4 [evolution] Stitching for OpenCV 4.0 * stitching: wrap Stitcher::create for bindings * provide method for consistent stitcher usage across languages * samples: add python stitching sample * port cpp stitching sample to python * stitching: consolidate Stitcher create methods * remove Stitcher::createDefault, it returns Stitcher, not Ptr<Stitcher> -> inconsistent API * deprecate cv::createStitcher and cv::createStitcherScans in favor of Stitcher::create * stitching: avoid anonymous enum in Stitcher * ORIG_RESOL should be double * add documentatiton * stitching: improve documentation in Stitcher * stitching: expose estimator in Stitcher * remove ABI hack * stitching: drop try_use_gpu flag * OCL will be used automatically through T-API in OCL-enable paths * CUDA won't be used unless user sets CUDA-enabled classes manually * stitching: drop FeaturesFinder * use Feature2D instead of FeaturesFinder * interoperability with features2d module * detach from dependency on xfeatures2d * features2d: fix compute and detect to work with UMat vectors * correctly pass UMats as UMats to allow OCL paths * support vector of UMats as output arg * stitching: use nearest interpolation for resizing masks * fix warnings
