imageAtomicExchange atomically stores the value of data into the texel at coordinate P and sample in the
       image bound to unit image, and returns the original value of the texel.

       imageAtomicExchange - atomically store supplied data into memory and return the original value from
       memory

image
           Specify the image unit into which to store data.

       P
           Specify the coordinate at which to store the data.

       sample
           When present, specifies the sample within the image to store into.

       data
           Specifies the data to exchange with that stored in the image.
