The java/awt/font/TextLayout/TestRotBounds/RotFontBoundsTest.java is an applet-based test for JDK-4650997. It displays series of rotated TextLayouts. It could be hard to analyse when all 8 rotations are displayed at once.

An ability to hide and show each individual rotation will help analyse the behaviour of TextLayout.

The test should be converted to a stand-alone app which uses the PassFailJFrame framework.
