Effects are applied to a shape that is generated from a merged text path.
The merged text path is created from text paths that are associated with
a text run. Boolean operations may be used to create the merged text
path. The merged text path removes any overlap and redundancy of the
characters within the text run. The shape that is generated from the
merged text path maintains the text path information that is associated
with the text run such that additional effects may be applied to the
shape.
