• hwcontext_vulkan : correctly download and upload flipped images

  hwcontext_vulkan : correctly download and upload flipped images
  We derive the destination buffer stride from the input stride,
  
  which meant if the image was flipped with a negative stride,
  
  we'd be FFALIGNING a negative number which ends up being huge,
  
  thus making the Vulkan buffer allocation fail and the whole
  
  image transfer fail.
  Only found out about this as OpenGL compositors can copy an entire
  
  image with a single call if its flipped, rather than iterate over
  
  each line.
