The text height and thickness settings were never implemented so they
didn't get updated when the options were changed. Added the missing
code to update both parameters.
Added text width parameter so text height and width do not need to be
the same value. Currently both the value and reference fields are set
to the same height and width. Please feel free to change this if you
feel the need to have separate text settings for both the value and
reference fields.
