graphics - Problem with hole filling using filledCurveToPolygons3D in MMA 10

I successfully used the filledCurveToPolygons3D function to create Graphics3D text in MMA 9 on a Windows 7 PC; see:

How can I create a 3D FilledCurve object?

However, when I installed MMA 10 on this very same machine and tried using this technique again, all the holes in the text are filled. I tried using the recommended changes to the RHS of processHoles that another user had had with MMA 9 on a Mac, but I still ended up with all the holes filled. The same problem shows up as well with the 2D function filledCurveToPolygons.
