The `width` value passed to `computeMinHeight` (if not -1) should be the result
of a call to `computeMinWidth(-1)` (depending on the result of
`getContentBias`; this is specified somewhere); if that function always
includes the insets, then subtracting them here should not result in a negative
value.
Of course, one can never be too careful.
I don't like the changing of the meaning of the `width` parameter here though
using parameter assignment.
