-/* Symbolic weight thresholds
- *
- * Constraint weights live on a continuum, but we use thresholds for simplicity's
- * sake, so we don't have to necessarily reason in terms of numeric values.
- *
- * The public API has a similar approach, where the symbolic constants are negative
- * values, and positive values are explicit weights. We map those values into
- * numeric values that the GtkConstraintSolver can plug into the linear equations
- * tableau.
