[Qt] Qt 4.6 Obsolete Classes

[Den Jean]

Hi Zeljko,

during the preparation of a Qt 4.6 version, 
I noticed that some classes are deprecated.
Could you remove/avoid the usage in lcl of those Qt classes.
http://doc.trolltech.com/4.6/obsoleteclasses.html

I think only QMatrix is used.
QMatrix -?> QTransform (available in 4.5.3)

  http://doc.trolltech.com/4.6/qmatrix.html#details
"...QTransform is the recommended transformation class in Qt..."

Though QMatrix is not in the list of Qt 4.6 all classes, 
  http://doc.trolltech.com/4.6/classes.html
it is still available in the Qt 4.6 code, so I added it already 
manually to the binding of 4.6. (so no hurry in removing it)

regards,

Den Jean
