    Add a --scale-from option
    
    A typical case for wanting to specify a scale on an output is making your
    framebuffer be one size and scaling it to fill an output of a different size.
    Instead of making the user calculate the scaling factors to be specified by
    --scale, add a new option, --scale-from, that lets the user specify the
    framebuffer size directly.  Compute the appropriate transform to achieve the
    desired target size.
