+1.4 A powerful qt device driver has been implemented
+
+Thanks to the efforts of Alban Rochel of the QSAS team, we now have a qt
+device driver which delivers the following 9 (!) devices: qtwidget, bmpqt,
+jpgqt, pngqt, ppmqt, tiffqt, epsqt, pdfqt, and svgqt. qtwidget is an
+elementary interactive device where, for now, the possible interactions
+consist of resizing the window and right clicking with the mouse to control
+paging.  The qtwidget overall size is expressed in pixels. bmpqt, jpgqt,
+pngqt, ppmqt, and tiffqt are file devices whose overal sizes are specified
+in pixels and whose output is BMP (Windows bitmap), JPEG, PNG, PPM (portable
+pixmap), and TIFF (tagged image file format) formatted files. epsqt, pdfqt,
+svgqt are file devices whose overall sizes are specified in points (1/72 of
+an inch) and whose output is EPS (encapsulated PostScript), PDF, and SVG
+formatted files.  The qt device driver is based on the powerful facilities
+of Qt4 so all qt devices implement variable opacity (alpha channel) effects
+(see example 3).  The qt devices also use system unicode fonts, and deal
+with CTL (complex text layout) languages automatically without any
+intervention required by the user.  (To show this, try qt device results
+from examples 23 [mathematical symbols] and 24 [CTL languages].)
+
+Our exhaustive Linux testing of the qt devices (which consisted of detailed
+comparisons for all our standard examples between qt device results and the
+corresponding cairo device results) indicates this device driver is mature,
+but testing on other platforms is requested to confirm that maturity.
+Qt-4.5 has some essential SVG functionality so we recommend that
+version (downloadable from http://www.qtsoftware.com/downloads for Linux,
+Mac OS X, and Windows) for svgqt.  Qt-4.5 is the version we have used for
+most of our testing, but limited testing for Qt-4.4 indicates that version
+should be fine for qt devices other than svgqt.
