Re: QT bug

[Isam Bayazidi <bayazidi at arabeyes dot org>]

Salam..
I am not sure what does KDE use, QPainter or QWidget .. when I tried to go 
through the code and see if drawText is called from this or that .. it seems 
that the KDE developers use the pointers to make code sneakers like myself 
runaway fast :-)

Anywhy it is indeed a direction probelm.. not a shaping one .. as you can 
notice that if the glyphs are arranged from right to left, shaping would be 
proper..
