While it isn't possible, or even advisable, to make all the list
box rows the same height, using a number of standard heights will
make the control center feel more harmoneous.

Adust the height of the list box rows in Color, Date & Time,
Mouse & Touchpad, Network, Privacy, Region & Language, Sharing
and Universal Access. Makes standard rows that contain labels
and/or controls 58px tall. Some other rows, such as those which
contain two lines of text, are allowed to be taller.
