[OpenJDK 2D-Dev] Freetype font rasteriser

Thanks for reporting this.

Another known problem is usage of embedded bitmaps in the LCD mode.

It will be good to file bugs for observed problems.
Until OpenJDK get own bug database - use 
http://bugs.sun.com/bugdatabase/ to report them.

And we also looking for fixes :)

True. Initially i had some subtle reasons to do this and they probably 
not applicable anymore (because i can not recall them).
I had plan to rewrite this but never got to this. Priority was to 
refactor architecture without breaking everything and
because of this freetype glue code did not enough attention.

Feel free to suggest (or even better submit) improvements.
Now it is much easier to accept contributions for this part of code.
