Update to 2.2.3. Changes are:

Qt 2.2.3 is a bugfix release. It keeps both forward and backward
compatibility (source and binary) with Qt 2.2.2


****************************************************************************
*			    General					   *
****************************************************************************

- Platform fixes for Red Hat 7.0, Unixware 7, SCO OpenServer 5.0.5,
  LinuxPPC, True64.

- Basic multihead support for MS-Windows 98/2000: Popup windows, tooltips
  and What's This? help texts now appear on the correct screen,
  QApplication::desktop() is now as big as the virtual screen.

- Documented previously internal QEmbed utility. The tool converts
  arbitrary files into C++ code. This is useful for including image
  files and other resources directly into your application rather than
  loading the data from external files. You find it in qt/tools/qembed.

- X11 only: Fixed font sizes on higher resolution displays. When
  asking for a specific point size, you should always receive a font
  with an adequate pixel size depending on the dpi value of the
  display. This was supposed to work before, but broke for certain cases
  on XFree 4.x.

- Many minor bugfixes and small improvements, see detailed lists below.
