There are still a few problems, because I made a few mistakes with
  file placing that I can only fix by committing, fixing and commiting.
  Also, the library isn't completely independent of the rest of Krita yet,
  see the TODO.
* Add an uml diagram of the histogram design.
* Add a meta registry -- that needs to be expanded so it becomes a central
  database for all the stuff we have in the myriad of singletons.
* Fix the HACKING file about getters and setters to conform to Qt standards.
