I think it would be clearer if we set these values depending on the
orientation, and then we just use scale_width, scaled_height below.

Don't use magic numbers here, use NONE and LANDSCAPE instead.

I don't think we need the tmp_ variables, we can just modify the
existing xoffset/yoffset.

Where does this end up? After the setup and before the pages? Isn't it
recommended to apply the rotation after the translation? I think we
could move this to spectre_gs_process, after the translate. We pass the
rotation to spectre_gs_process and when it's != NONE we inject the
rotate command there. What do you think?
