It seems like what would make sense is for stencils to carry their own skyline 
information, much like they carry their own dimension information.  That way, 
we would replace a skyline in the same way that we replace the dimension.

This type of storage within the stencil data structure itself would be 
consistent with the current use of skylines.  In fact, the X and Y dimensions 
would no longer need to be specified and could come directly from the skylines.
