 Added back in raster optimising, it's not perfect but it's mostly there. Only a little slow parsing white vertical space now.
 Found that raster optimisation code seems to be changing the pixel data at the end of the line somewhere. I'm not sure how since it's meant to just be cutting part of the data line out not changing it. will need to investigate further.
 Added option to the menu for users to disable raster optimisations.
