A number field with a spinner and a preset list (stroke weight, font
size, leading…) was three boxes side by side: the field came out a
point taller than the spinner and the chevron, and each joint had two
borders. The field is now exactly as tall as the other controls of a
row, with its text centred, and the three parts share their borders.
num_field draws its box with the panel text fields' code instead of a
copy of it.
