Note that the computation for bottom rotations is wrong, forcing the user to uses arbitrary rotations.
The correct computation is `(180 - component rot) + angle` but the plugin does `180 - (component rot + angle)`.
This option forces the wrong computation for compatibility.
This option also controls the way offset signs are interpreted. When enabled the offsets matches this plugin,
when disabled matches the interpretation used by the matthewlai/JLCKicadTools plugin.
