// ...actually, it tells us two things: the "minimum size" and the "natural size".

// The "minimum size" is the smallest size we /can/ display /anything/. The "natural size" is the smallest size we would /prefer/ to display.
|
|
// The difference? Minimum size takes into account things like truncation with ellipses: the minimum size of a label can allot just the ellipses!

|
// So we use the natural size instead.

// There is a warning about height-for-width controls, but in my tests this isn't an issue.
