We already converted coordinates from root to virtual screen, we
shouldn't need to remap them.

This is actually no-op because when window == root_window, hwnd is
the desktop window. In which case it isn't RTL, and MapWindowPoints is
no-op too.

It makes things less confusing and it will help later cases when we get
root-relative coordinates for other windows.

Based on a patch from Gabriel Ivăncescu <gabrielopcode@gmail.com>.
