| * 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). |
