Pre-rotate output for transformed monitors

On: files are saved at native resolution, already rotated (disable transform-awareness in your wallpaper tool). Off: saved at the monitor's on-screen footprint, unrotated (let the tool rotate).

Drag the frames over the image to aim them. Scroll to zoom (or use the slider). The main monitor keeps the focus; side monitors fill space.
