Returns the distance that the cursor has moved since the last frame.
x, y = GetCursorDelta()
- number - Distance along the X axis that the cursor has travelled.
- number - Distance along the Y axis that the cursor has travelled.
- If the cursor hasn't moved between two frames, this function will return zeroes.
- Values returned by this function are independent of UI scaling. The GetScaledCursorDelta utility function can be used to apply the effective scale of UIParent to the returned values.
