GNOME Shell Magnifier Advanced Settings and Testing

[Robert cole <rkcole72984 gmail com>]

Hello again, everyone.

As you may have probably guessed by my heavy torrent of e-mails (sorry), 
I am really trying to do some testing with the GNOME shell Magnifier.
I saw some screenshots of a more advanced dialog for magnifier settings 
on the GNOME Shell magnification page [1]. I also read some references 
to a testing dialog here [2], but it seems that this has been 
discontinued (?). Under GNOME 3.2 the Universal Access dialog does not 
offer much in the way of magnification settings, so I was wondering if 
there was a different package for GNOME 3.2 which could be used to alter 
settings. I have been reading through this file:
/usr/share/gnome-shell/js/ui/magnifier.js

and, unfortunately, I really would not know where to begin as far as the 
settings are concerned (with the only exclusion being that of the 
MOUSE_POLL_FREQUENCY variable). I only have very basic programming 
skills, so I have no idea where to begin in this.
I guess the other question I should ask is this: Is there a need for 
testers as concerning the magnifier? I have used screen magnifiers in 
Windows for years, and I have been a sole Linux user for the past five 
years or so. If I could be of any use to those developing the magnifier, 
I would be more than glad to do what I can.
If there is no longer a dialog for the more advanced settings of the 
magnifier, is there a document some place which explains how to set 
different values using GSettings? I have never used GSettings, but I 
could learn to do so.
Thanks for taking the time to read through my tons of e-mails, and for 
any help and guidance.
Take care.
