Vladimir	90be83ae99	Fix an arg for calcHist() in demos `float* histRange = { range };` doesn't make much sense. `histRange` is an array of array(s), so it should have a type of ptr to ptr. Strangely some domos are correct as well as the example for the function https://docs.opencv.org/master/d6/dc7/group__imgproc__hist.html#ga4b2b5fd75503ff9e6844cc4dcdaed35d	3 years ago
