I've even managed to clip it correctly now:

 block!8  = minx% - (scrollx% - icminx%)
   IF scrollx% > icminx% THEN block!8  = minx%+4
 block!12 = maxy% - (scrolly% - icminy%)
 block!16 = minx% - (scrollx% - icmaxx%)
   IF maxx% + (scrollx% - minx%) < icmaxx% THEN block!16 = maxx%-4
 block!20 = maxy% - (scrolly% - icmaxy%)

But I still don't understand it...
