Resizing the likes suggested are manipulation functions. Not out of 
scope, I most likely will not be implementing them.
My goal is only to do the simpler image manipulation functions as I 
would have to implement them twice each. One to work with ranges the 
other to whole sale modify the image to be that way and may allocate in 
the process.

Canvas is definitely and 100% out of scope however. It's a great idea 
and something we need long term. Just not something I can do right now.
Also need to add that to specification document as a follow on work and 
out of scope.
