Fix getTouch() return status upon bounds overflow

Browse Source 
- When the post-remapped coordinates exceed screen bounds, `getTouch()` was returning a "valid" status without updating the coordinates. This would result in spurious touch detection events at the screen boundaries.
- The fix ensures that the return value is set to "invalid" in this boundary condition.
