Hello strk,

Uhm, I missed this message :(

Anyway, I'm not very happy with it because it would result in very
coarse results and/or probably even worse CPU usage.


  - detecting the correct rectangles and re-computing (mergin) valid
    rectangles in the final step won't be faster than dealing with the
    original rect instances.

  - when the rectangles are too coarse this might invoke useless
    drawing of perhabs very complex nearby characters.

I prefer strk's class design, I have no problem implementing it...
