Revision control
++ Here is a list of (major) changes in Qt from 0.93 to 0.95.
++
++ Bug-fixes, optimizations and much improved documentation, of course.
++
++ There are few changes in the API (Qt header files).
++
++
++ QPixmap:
++ --------
++ Can draw transparent pixmaps. Call QPixmap::setMask(QBitmap) to
++ set a mask.
++
++
++ QPainter:
++ ---------
++ Unified transformation. setWindow() and setViewport() now use
++ the same code as setWorldXForm() etc.
++ Internal xform routines have been optimized.
++
++
++ QButton:
++ --------
++ isUp() is obsolete, use !isDown() instead.
++ isOff() is obsolete, use !isOn() instead.
++ switchOn() is obsolete, use setOn(TRUE) instead.
++ switchOff() is obsolete, use setOn(FALSE) instead.
++
++
++ QPushButton:
++ ------------
++ A push button can now be a toggle button.
++
++
++ QWidget:
++ --------
++ isActive() was never used and is now obsolete.
++
++
++ QTextStream:
++ ------------
++ eos() renamed to eof() for iostream compatibility.
++ operator>> for double, float, char*, QString are implemented
++ get() and getline() added.
++
++
++ QDataStream:
++ ------------
++ eos() renamed to eof() for iostream compatibility.
++
++
++ QImage:
++ -------
++ Scanline data is aligned on a 32 bit boundary (it used to be 8
++ bits). Conversion to and from QPixmap is now faster.
