Browse source 
Fixed the verticalAnchorType and horizontalAnchorType calculation

The anchorID 0, 1 and 2 should correspond to verticalAnchorType=ANCHOR_TYPE_START, anchorID 3, 4, 5 is ANCHOR_TYPE_MIDDLE, anchorID 6, 7 and 8 is ANCHOR_TYPE_END

The anchorID 0, 3 and 6 should correspond to horizzonatlAnchor=ANCHOR_TYPE_START, anchorID 1, 4, 7 is ANCHOR_TYPE_MIDDLE, anchorID 2, 5 and 8 is ANCHOR_TYPE_END
