--- Comment #11 from Massimo <sixtysix at inwind.it> ---
It is also possible to round intersections to their nearest integer,
it is a little more elaborate:

it is necessary to

properly round the integer quotient to the nearest integer,         
change the cairo_bo_intersect_ordinate 'exactness' member to hold   
say {EXCESS, EXACT, DEFECT } values, and split INTERSECTION events  
in INTERSECTION_ABOVE and INTERSECTION_BELOW events which should    
be processed


with that approach few image tests that fail with the patch
above do pass.
