Input point filters and monitors can be invoked multiple times for a single input point under the following conditions:
- When the TAB key is pressed after a digitizer motion event, the object snap candidate for the cursor position is cycled. As soon as the cursor motion is detected, the object snap candidate cycling index is reset.
- When a registered input point filter returns a Boolean indicating to retry for a point, the system prompts for a new event, not returning the point from the event that will be retried.
