Started the work to handle checkboxes. For now, we draw just a red rectangle; when we do events this will change color dynamically. When I hook up the control to its parent, I will move from these rectangles to the actual checkbox images. In the meantime, fix some pointer bugs in imagelist_windows.c as well.
