The old impl was using get/put_pixel(), the new slow one is using the get/put_pixel_fast(), and the new default flip_image() is using just raw pointers. Added some utilites like random_image() for testing purposes, and DOC_DISPATCH_BY_COLOR_MODE() macros to avoid switch/case for each color mode. In a future these might use generic lambdas.
