This commit enhances the output transform command with options for a relative transform, i.e. the provided transform will be applied as an offset to the current transform. Append `clockwise` to rotate clockwise from the current rotation, or `anticlockwise` to rotate in the opposite direction. For example, if the output LVDS-1 is rotated 90 degrees clockwise, the command `output LVDS-1 transform 90 clockwise` will rotate the display to 180 degrees. All transform options are supported, including flipped transforms. Relative transforms can only be applied to a single output and cannot be used with a wildcard (*) output specifier.
