A Scala port of the Kiwi Java and Kiwi Haxe implementations of the Cassowary constraint solving algorithm
val solver = new Solver
val x = new Variable
val y = new Variable
solver += x == 20
solver += x + 2 == y + 10
!solver
println(x.value, y.value)
// (20.0, 12.0)Those three lines with solver use the short form of the following.
solver.addConstraint(Symbolics.equals(x, 20))
solver.addConstraint(Symbolics.equals(Symbolics.add(x, 2), Symbolics.add(y, 10)))
solver.updateVariables()
