I am currently using a list of tuples - [(Int,Int,Int)] to represent an
image buffer. You can see it in the getImageByteString
function at https://github.com/ckkashyap/Chitra/blob/master/RFB/Encoding.hs
Looks like this is pretty slow, and hence I am exploring Arrays.
I wonder if working with [Word8] will also suffer from performance hit?
