This parameter is usefull only for oblong pads (it can be used for other 
shapes, but without any interest).
this is the offset between the pad hole and the pad shape (you must 
understand here pad shape = copper area around the hole)
Most of cases, the hole is the centre of the shape (m_Offset = 0).
But some board designers use oblong pads with a hole moved to one of the 
oblong pad shape ends.
In all cases the pad position is the pad hole.
The physical shape position (used to draw it for instance) is pad 
position (m_Pos) + m_Offset.
D_PAD::ReturnShapePos() returns the physical shape position according to 
the offset and the pad rotation.
