It is a legal term
that you will see
at the end of a Complaint.
It is how the plaintiff specifies what relief

Some states use the word Pray or Prayer and some don't.
It's anachronistic, but it does not imply "praying" to government in the same fashion that we pray to Almighty God.
I'm sure someone can pick a better word if they so desire.
It's not my petition and I have no skin in the game, just explaining terminology.
I use GIMP.
It is a sophisticated, mature, stable, open source graphics package that is available on Linux.
GIMP is difficult to learn but very powerful.
You could try a web search and see if downloads are available for your platform.
