Feature Request - Scale/Zoom Features for Visually Impaired

Hi friends. I'm submitting this bug/feature-request in an effort to voice support behind any and all current visually accessible features, including but not limited to: Display Scaling, Desktop Zoom with keyboard toggle, and High Contrast Text.

I work for a public school district with a lot of Ubuntu machines in use on a daily basis. These features, and I cannot stress this enough, are critical to these kids who rely on it to enhance their computing experience in class. Once some simple settings are toggled (whether in the current System Settings or something like Unity Tweak Tool), it's been pretty incredible to see students give you the nod that "I got it from here" and continue onward with their learning.

I'm sure it would benefit a multitude of other folks of any age range as well who fit this paradigm of being able to utilize these visually assisted features. The current Unity 7 does an excellent job of this. Similar capability in Unity 8 would simply be a gold set of features to have.

Thank you for your time, consideration, and continued hard work!
