Uneven line spacing

I am using figtext() to add text to a figure. I have noticed that with
muti-line text, the linespacing will look uneven due to letters which
extend below.

For example: figtext(0,0,"ppp\naaa\nggg\nsss")
Will look something like this (exaggerated)

ppp

aaa
ggg

Sss

With a larger space under letters like p and g

I tried some different fonts but that did not seem to make any
difference
Is there a way to correct this so it looks even?
