I'm not sure but I think whoever wrote that intended that
at that point in the code the endpoints would've been exchanged
so that dy > 0, or something of that sort.
There are actually some other bugs here and there in
imlib2 in various parts.. eg. the polygon drawing code has one
that ocurrs when all vertices are 'active'.. a somewhat uncommon
case and no one seems to have reported it so far. It also uses
a 'thick' kind of filling which I don't think is what one would
want for evas say.
Clearly whoever wrote that stuff seems to have left things
in imlib2 languish since no improvements or fixes have ever been
sent on anything. :(
