QDeclarativeItem::clip misses a note saying if it is enabled or not by default

The documentation says
************
clip : bool
This property holds whether clipping is enabled.
if clipping is enabled, an item will clip its own painting, as well as the painting of its children, to its bounding rectangle.
Non-rectangular clipping regions are not supported for performance reasons.

Access functions:
bool clip () const
void setClip ( bool )
************

It is difficult for the user to know if clipping is enabled by default or not
