CheckBox

Remarks

Three elements: the box, the tick inside it, and the label. The tick is an Icon rather than something drawn here, so that a theme can replace it with its own geometry, and it is present in the tree whether or not the box is ticked — the stylesheet hides it with display: none, which costs nothing and keeps "is it ticked" a single fact in a single place.

Indeterminate is a third appearance rather than a third value. IsChecked stays a bool, because a tri-state checkbox that a caller has to handle three cases for is a tri-state checkbox nobody handles all three cases for. What IsIndeterminate means is "the box does not currently reflect IsChecked, because the things it stands for disagree" — the parent of a half-ticked list — and clicking it resolves it, which is what it is for.
