createRowDimensionRatio(
    SolverVariable variableA,
    SolverVariable variableB,
    SolverVariable variableC,
    SolverVariable variableD,
    float ratio
)

Create a constraint to express A = B + (C - D) * ratio We use this for ratio, where for example Right = Left + (Bottom - Top) * percent
