-    \value Qt4CompatiblePainting Compatibility hint telling the engine to use the
-    same X11 based fill rules as in Qt 4, where aliased rendering is offset
-    by slightly less than half a pixel. Also will treat default constructed pens
-    as cosmetic. Potentially useful when porting a Qt 4 application to Qt 5.

     \value LosslessImageRendering Use a lossless image rendering, whenever possible.
     Currently, this hint is only used when QPainter is employed to output a PDF
