Minimum size is changed to 700x512. I arrived at this number from testing
the minimum sizes that I felt the settings UI was still perfectly usable
and readable. Any smaller, and things became difficult to see and adjust.
As a note, this does increase the minum width of the settings window, as
the previous minimum allowed you to cut off objects and render the window
too small to be usable.
