More work on fixing font anti-aliasing regressions introduced in 5.2.147.  Fairly confident this is sorted now

Root cause : we had to switch some graphics drawing commands as older commands work with Java8 but do not work with later java versions. The 'substitutes' don't work the same and we didn't realise this.  Reviewing original java source code which is no longer supported but latest javas fairly confident now we have replicated the original removed behaviours now.
