Added Fix For Background Clearing

It should only occur on the first visible view which is the legacy Game
Maker behaviour. In Stupido you can choose which views clear the
background, should be implemented in the future. This fixes my earlier fix
as I was only checking for view 0 to be the first view, some games like
Animation Platform Example turn off the first view and enable the second,
so this fix is the proper way to check for the first view.
