Make QPen default to 1-width non-cosmetic.

Browse Source 
Use the Qt4CompatiblePainting render hint when painting with QPainter to
treat default constructed QPens as cosmetic still.

The NonCosmeticDefaultPen render hint gets documented as obsolete, since
it was in any case not respected by the raster nor OpenGL paint engine.

rectangle filling. It's possible to still get the old behavior by setting the
QPainter::Qt4CompatiblePainting render hint.
* Behavioral change regarding QPen: The default QPen constructors now create a
1-width non-cosmetic pen as opposed to a 0-width cosmetic pen. The old
behavior can be emulated by setting the QPainter::Qt4CompatiblePainting
render hint when painting.
