Lets say I'm creating an Image of, oh lets say a glazed Doughnut. Now, I've created the general outline and to achieve the hole in the center, I created a smaller circle shape and used the Path>Division command to cut out the center. No problems here. Now, since its a glazed doughnut, it has lots of specular highlights and in this particular image, one of the highlights on the inside of the doughnut needs to go all the way to the inner edge of said hole.

Imagine the highlight on the bottom left (7 o'clock ish) was going all the way to the center.
What would you suggest be the best approach to this problem.
(the "hole" in my image (secret: don't ask why) will be overlaying something behind it, if that helps/opens up to more options)
THANKS!
