The function create_view is only called when reusing the image's memory. I
guess I don't understand what you mean.

When the user recreates an image with a different _align_in_bytes we need
to reallocate the memory. I added this condition to the code. If the
alignment doesn't change then I don't need to update the member.

Good question! For whatever reason I thought it takes in a memory pointer.
But on a closer look it I realize that's nonsense. I have added the new
code.

Thanks for helping out!
