0f2d8f854a Prevent false-positive in "Stale Shift Registers" 
Sprite zero is no longer on a scanline with visible pixels.
I also ran some checks for false-positives, flagging sprite zero hits entirely because sprite zero exists.
I also ran some checks afterwards for what happens if the sprite X position wasn't zero.

e13d252cb5 Fixed some comments in the new test
