ComputeFootprintShift()

bool ComputeFootprintShift	(	const FOOTPRINT &	aExisting,
		const FOOTPRINT &	aNew,
		VECTOR2I &	aShift,
		EDA_ANGLE &	aAngleShift )

Compute position and angle shift between two footprints.

This will only happen when the new footprint has a different origin or has been rotated compared to the existing footprint. Most of the time, this returns a null shift.

The shift is computed based on pad positions and assumes that there are at least two non-coincident pads with unique numbers that are the same in both footprints.
