RFR: 8226789: Path rendered incorrectly when it goes outside the clipping region

[Laurent Bourgès]

Hi,

Please review this bug fix in Marlin renderer's path clipper
:https://bugs.openjdk.java.net/browse/JDK-8226789https://github.com/javafxports/openjdk-jfx/pull/534

PS: I will propose another fix soon to JDK14 / Marlin renderer (java2d)

Laurent
