/* Robot.betterMouseMove is a function that's meant to fix Robot.mouseMove when dealing with Windows's
display scaling in order to make text easier to see. The 'scaleFactor' is the actual scaling factor
as a float > 1.0f.

This is the error vector field that represents the error caused by Robot.mouseMove in which to move
in the x and y direction towards its destination. It's not that useful in hindsight, but kind of cool
that one can model the error as a mathematical function.

"Error" Vector Field: F(x, y) = f(x, y) * i + g(x, y) * j
    f(x, y) = (-x + t_x) / (width - t_x)
