+/**
+ * Manual test for:
+ * JDK-8057986: freetype code to get glyph outline does not handle initial control point properly
+ *
+ * Manual repro recipe:
+ * (cd test/java/awt/font/GlyphVector/ && javac GlyphVectorOutline.java && wget -q -O/tmp/msgothic.ttc https://browserlinux-jp.googlecode.com/files/msgothic.ttc && java GlyphVectorOutline /tmp/msgothic.ttc /tmp/katakana.png)
+ *
+ * Then examine the two rendered Japanese characters in the png file.
+ *
+ * Renders text to a PNG by
+ * 1. using the native Graphics2D#drawGlyphVector implementation
+ * 2. filling in the result of GlyphVector#getOutline
+ *
+ * Should be the same but is different for some CJK characters
+ * (e.g. Katakana character \u30AF).
