Fix T66501: Eraser very slow with guides 

After testing the file, the problem was related to the fill material. As the fill material had the alpha channel set to 1.0, the fill triangulation was calculated, but the fill was disabled.

Now, the fill flag is checked in order to avoid fill triangulation update.
