Feature request - add remove holes from mask

When we want to fast cut off the shape from eg. scanned picture usually use magic wand. Unfortunately scanned pictures contains sometimes a dust. If we see that our shape is properly selected and try to trim picture to selected area, it turns out that the task is unworkable because of almost invisible particles of dust. The Corel Paint solved this problem many years ago by adding option "remove holes from selection". It works perfectly. Please implement exactly the same functionality.
