Review request for 8169294:

[Laurent Bourgès]

Hi,

Please review this Path2D fix improving its storage growth algorithm as
done in java2d:
JBS: https://bugs.openjdk.java.net/browse/JDK-8169294
Webrev: http://cr.openjdk.java.net/~lbourges/fx/path2D/

PS: I converted the former jtreg test to JUnit test for OpenJFX. I hope it
is correct, as I was not able to run this test within gradle (but it works
in netbeans)

Best regards,
Laurent
