MarkerPenRampingPowerIsPercentageOfPen Property

Whether the power in RampingStartSegments and RampingEndSegments (except -1, which always means the pen's full power) is a fraction of the pen's power, instead of an absolute fraction of the max power. This lets the ramp shape track changes to the pen's power.
