sim.adjustCoords wrong description

This function takes mouse coordinates and returns where they should be, accounting for the zoom window. It doesn't move the zoom window.

(I would submit a PR but i'm lazy and only have 20 minutes right now)

Locate the description for sim.adjustCoords and read the surrounding documentation to confirm how the function is described. Update it to say that the function adjusts mouse coordinates for the zoom window without moving that window; done means the description matches the stated behavior and the function remains unchanged.
