     To create your own custom effect, create a subclass of QGraphicsEffect (or

-    such as a pointer to the item that is rendering the effect, any cached

+    you can call sourcePixmap() to get a pixmap of the graphics effect source
+    which you can then process.
 
     If your effect changes, use update() to request for a redraw. If your
     custom effect changes the bounding rectangle of the source, e.g., a radial
     glow effect may need to apply an extra margin, you can reimplement the
-    virtual boundingRectFor() function, and call updateBoundingRect() to notify
