HattrickGenerator	115e471515	Merge pull request #19967 from HattrickGenerator:master * Adding functions rbegin() and rend() functions to matrix class. This is important to be more standard compliant with C++ and an ever increasing number of people using standard algorithms for better code readability- and maintainability. The functions are copy pated from their counterparts (even though they should probably call the counterparts but this gave me some troube). They return iterators using std::reverse_iterators Follow up of an open feature request: https://github.com/opencv/opencv/issues/4641 * Fix rbegin() and rend() and provide tests for them * Removing unnecessary whitespaces * Adding rbegin and rend to Mat_ class with the right parameters so we don't need to repeat the template argument. An instantiating cv::Mat_<int> for example can call it's rbegin() function and doesn't need rbegin<int>() with this convience addition. Follows what is done for forward iterators * static cast the vector size (return size_t) to an int (that is required for opencv mat constructor) Co-authored-by: Stefan <stefan.gerl@tum.de>	4 years ago
