If true, then simplify the output geometry by replacing nearly straight
chains of short edges with a single long edge.
The combined effect of snapping and simplifying will not change the
input by more than the guaranteed tolerances (see the list documented
with the SnapFunction class). For example, simplified edges are
guaranteed to pass within snap_radius() of the *original* positions of
all vertices that were removed from that edge. This is a much tighter
guarantee than can be achieved by snapping and simplifying separately.
However, note that this option does not guarantee idempotency. In
other words, simplifying geometry that has already been simplified once
may simplify it further. (This is unavoidable, since tolerances are
measured with respect to the original geometry, which is no longer
available when the geometry is simplified a second time.)
When the output consists of multiple layers, simplification is
guaranteed to be consistent: for example, edge chains are simplified in
the same way across layers, and simplification preserves topological
relationships between layers (e.g., no crossing edges will be created).
Note that edge chains in different layers do not need to be identical
(or even have the same number of vertices, etc) in order to be
simplified together. All that is required is that they are close
enough together so that the same simplified edge can meet all of their
individual snapping guarantees.
Note that edge chains are approximated as parametric curves rather than
point sets. This means that if an edge chain backtracks on itself (for
example, ABCDEFEDCDEFGH) then such backtracking will be preserved to
within snap_radius() (for example, if the preceding point were all in a
straight line then the edge chain would be simplified to ACFCFH, noting
that C and F have degree > 2 and therefore can't be simplified away).
Simplified edges are assigned all labels associated with the edges of
the simplified chain.
For this option to have any effect, a SnapFunction with a non-zero
snap_radius() must be specified. Also note that vertices specified
using ForceVertex are never simplified away.
