The progress bar _is_ linear with the offset in the target image. The 
non-linearity you might observe is most likely a side-effect of dynamic 
images. Reading/writing them is extremely fast if there is just zeroes 
in a certain area. Any good ideas how to address this in an image format 
independent way would be highly appreciated.
