Moar glitches!!
OK well, that's better I guess

For now... Mario is still clipping some of the time, through blocks, but
a lot of the time he is A OK
Debugging the wall stick

When Mario jumps, there is a special case in which lines that aught to
intersect are not doing so. In this case, the collision behaves in the
old way and bounces mario in the wrong direction.
The collision surface of the tile needs to be 1 pixel wider

I ran a missed collision through wolfram and noticed that it was missing
the collision (over or under shooting the tile). Moving the collision
wall by one pixel resolved this.
