offset specifies the offset, in pixels, of the control side
from the attachment position.
If the offset is positive, then the control side is offset
to the right of or below the attachment position. If it is
negative, then the control side is offset to the left of or
above the attachment position.
This is equivalent to the "b" term in the equation y = ax + b.
The default value is 0.
