Validation script and image URLs check out fine. Extension functionality and API usage not checked.

The only change I'd request for the tool is to allow unselect on the fog brush tool when selecting the icon again (so if it's currently selected, clicking again removes the brush size option like how the fog style tool works).

Just as a general piece of feedback the documentation makes it seem like using the tool will automatically reveal the fog but this only happens when fog cutting is enabled. This is fine (and probably preferred) but it might be good to clarify this in the docs.

Thanks for the feedback, those issues have now been resolved.

Thanks! The only thing is now the fog brush tool can't be toggled on again 😅

Reproduction goes:

1. Select fog paint brush (the brush size bar is now open)
2. Select fog paint brush again (the brush size bar is now closed)
3. Select paint brush a third time (the bar doesn't open)

Sorry, it's a bit of a picky one!
