This removes the tooltip due to being zero or negative information, and
also changes the description of the setting to not contain the word
"mirror", which will hopefully quash the "this is where I would place a
mirror to my screen to achieve what I want" interpretation which seems
to be a minority interpretation.
The first time this was complained about I figured this was probably a
one guy issue, but now it's happened twice, and I never want to see this
conversation again.
