Detailed Description

Return (or copy into dst) a subregion of src, but with the scanlines exchanged vertically (flip), or columns exchanged horizontally (flop), or transposed across the diagonal by swapping rows for columns (transpose) within the display/full window. In other words,

   flip                 flop               transpose
