Edge-based camera movement, How can I make it smoother/continuous?

@InoPeanut

apply both the upward and leftward movement at the same time when the mouse is at a corner, resulting in a diagonal camera motion

So it’s not about smoothness per se, you want specific direction. Let’s say this is our view and the green arrow is my cursor touching the top edge of the play area:

How should the camera move?

• along the orange vector?
• along the blue vector?
• is it only the 100x100 corner that triggers diagonal movement? Or are values in-between also allowed - as in, the camera moves slightly to the right but mostly upwards in this example?
