ramapcsx2 ef8fe6639e GSdx: 
- Found out that the blur detection filter was busted for some time now.
It worked by chance, due to the pixel crop hack.
Disabled that hack now and made PCSX2's GS frame handle that functionality instead.
This is a somewhat nicer method, although users of 4:3 and 16:9 aspect ratios might get flickering pixels on the borders again.
I'll see if I can think of something for those cases, should there be demand for it.
