Pixel Sorting visualization for each horizontal line individually on a colorful cat img [900x853]

Each line is individually sorted using quicksort.
The program when in autoloop chooses how the line is sorted, the direction of sorting and how much of the line must be sorted using quicksort lower and higher indexes parameter variables. When autoloop is not enabled the sorting is controlled by the x-axis of the mouse movement over the image.
