[OpenJDK 2D-Dev] RFR: JDK-8187100: support Variation Selectors (Resend)

[Steven R. Loomis]

(Retrying as actual text)

Support Unicode Variation Selectors.

Code by my colleague Toshio Nakamura,  I added a simple test, and include a
test that was part of JDK 8187100. (Both tests are run manually.)

Bug: https://bugs.openjdk.java.net/browse/JDK-8187100
Webrev: http://cr.openjdk.java.net/~srl/8187100/webrev.00/
