Initial low vision features added. xzoom needs to be installed for magnification. This first implementation is probably terrible, feedback welcome for improvement. Screen lock can now happen when I38 starts. As a reminder, it's not as secure as one of the system lockers, but it is screen reader accessible and should keep casual snoopers thwarted.
