That how it is usually done. So that code is repeated in various 
applications, the behavior is neither consistent nor correct (see my 
approach to pixel independent rendering), there is duplicated effort, 
many bugs appears, etc. Please do read 
http://www.jvuletich.org/Smalltalks2007/St2007VuletichMorphic3TalkProposal.pdf 
. Also read http://www.jvuletich.org/Morphic3/TheFutureOfTheGUI_02.html 
and http://www.jvuletich.org/Morphic3/TheFutureOfTheGUI_032.html . I try 
to make my point there. I don't know what to say but repeat what I wrote 
there. If I'm not clear enough or you don't agree with me, tell me!

Cheers,
