Renamed com.sun.opengl.utils to com.sun.opengl.util. Moved
TextureIO-related classes to com.sun.opengl.util.texture and TextureProvider, TextureWriter and format-specific readers to com.sun.opengl.util.texture.spi. Renamed BufferUtils to BufferUtil. Added ImageUtil and FileUtil. Cleaned up javadoc. Updated demos. Cleaned up some imports. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@538 232f8b59-042b-4e1e-8c03-345bb8c30851
