Here's the code this revision (3).
#!/usr/bin/env python
# bibo-text.py
# Created by TT
# This plug-in will accept a background layer, center-x, center-y and a sentence/phrase with multiple words separated by spaces.
# It will then animate by resizing the first word smaller and smaller then switches and resizes 2nd words larger and larger like as if you're breathing in and out.

# Rel 1: Initial release
# Rel 2: MareroQ on http://gimpchat.com/viewtopic.php?f=9&t=20604&start=10#p284795 prefers the word change when the text is small or when we just finished exhaling
# so I added a "word per breath" toggle
# Rel 3: MareroQ on http://gimpchat.com/viewtopic.php?f=9&t=20604&p=284804#p284804 recommended ability to change start and end opacity
# so I added these 2 input params
# And ability to choose Use Image Center toggle
