+/**
+ * Tests for bug 463, where gluScaleImage uses up all system memory. This was due to creating millions of
+ * 4-byte direct buffer objects inside the tight loops of Image.fill_image() and Image.empty_image(). Since
+ * the JVM apparently can only allocate direct buffer in 4MB chunks, each 4-byte buffer cost us a million times
+ * the memory it should have. Changing the constructor of Type_Widget.java back to non-direct buffer (like it
+ * was in JOGL 1) solves the problem.
