Auto-filling can be problematic in brush/erase mode

[cnzqy1]

In brush mode, if I hold down the right mouse button and draw a full circle, the enclosed area is automatically erased (rather than just the outline). Is this the expected behavior? This is problematic since sometimes a cell is overfilled and I want to clean up the annotation by following along the membrane, but instead the whole cell is erased.

Maybe this is related to #3698? In that case filling should only happen in painting and not in erasing. Also, it would be helpful to expose a setting to toggle the fill function on/off since sometimes there are annular structures.

Thank you for opening this issue! Right now, this is indeed expected behavior, but your concerns make perfect sense. We will think about how to easily disable the "auto-fill" feature (maybe by default when erasing). We'll keep you up to date in this issue.

@cnzqy1 We decided to add an option to turn off this auto-fill feature.

We decided to add an option to turn off this auto-fill feature.

After another discussion we came to the conclusion to just disable the autofill feature when using the brush to erase annotated data. (#4729)

Thanks for the update! Yeah, I couldn't quite think of a use case where auto-fill is needed for erasing.
