not sure what type of vignette you're talking about, but to apply one as i  
used to wile enlarging & developing prints the old way (optically &  
chemically), i just select an ellipse from upper left to lower right  
corner, invert the selection, and feather it according to image size. this  
allows me to either lighten or darken the corner areas, subtly focusing  
attention on the middle region.

if that's the type of vignette you're looking for, i don't think any tool  
can do that better than the plain ellipse selection tool.
