Subject: tor-scan-converter: can't do_fullrow when intersection in row +
|
||
|
|
0.5subrow
|
||
|
|
|
||
|
|
the active edges list must be left sorted at the next possible use
|
||
|
|
and since full_row does not deal with intersections it is not usable
|
||
|
|
when there is an intersection in the top half of the next row first
|
||
|
|
subrow
