- \value NonCosmeticDefaultPen The engine should interpret pens with a width
- of 0 (which otherwise enables QPen::isCosmetic()) as being a non-cosmetic
- pen with a width of 1.
+ \value NonCosmeticDefaultPen This value is obsolete, the default for QPen
+ is now non-cosmetic.
+
+ \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.
