While I'm here make things even easier to upgrade for next time. More tidy
up to come later.
Changelog:
Qt 2.2.4 is a bugfix release. It keeps both forward and backward
compatibility (source and binary) with Qt 2.2.3
****************************************************************************

- Platform and Compiler fixes for AIX and BSDi. Building a Qt DLL with
the Borland Builder is again supported.
- Printing quality and postscript output on X11 has been improved.
The page and text formatting now handles different Windows versions
correctly.
- Image loading of PNG and GIF files is much more robust against broken
files.
- On X11, popup menus do not grab the keyboard anymore, but rely on
and enforce the application to have focus. This works around an X11
bug where deadkeys do not work while the keyboard is grabbed.
- Many minor bugfixes and small improvements, see detailed lists below.

****************************************************************************
* Qt/Embedded-specific changes *
****************************************************************************
- Binary compatibility is NOT maintained with previous Qt/Embedded release,
you will need to recompile any old executables to use with this release.
- Source compatibility is NOT maintained with Qt/Embedded-specific functions.
You may get minor compilation errors if you have used previous
- QCopChannel now inherits QObject. If you have multiply-inherited a QObject
subclass and QCopChannel, you should instead connect your QObject to the
QCopChannel::received() signal.
- The identifier "TTF" in fontdir is now "FT". This reflects the fact that
the FreeType library supports Type1, Windows FNT, and other font formats
in addition to TrueType. FreeType 2.0.1 is now used (src/3rdparty/freetype).
- 16bpp support in QVFb.
- QDirectPainter experimental direct-video access.
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.

When asking for a specific point size, you should always
