2.4.4.370 UseGroupGradient
The UseGroupGradient cell is a PtgBool parse token that specifies whether a subshape uses the gradient starting and ending points of its parent shape for fill gradient. It MUST have a ShapeSheet_Type or StyleSheet_Type parent element.
A value of one specifies that the subshape uses the gradient starting and ending points of its parent shape for fill gradient; a value of zero specifies that the subshape uses its own gradient starting and ending points for fill gradient. If the shape is not a subshape, the token is used during formula evaluation only.
