Hi again, for everyone willing to test, here is another build: https://drive.google.com/open?id=0Bxxu6Mh3pHubWGhKMHVPRER4MkU
It applies the same kind of optimisation to some places where more than one line/segment is drawn (i.e., when drawing polygons or text - which is quite much). Again, feedback would be very welcome to be able to judge whether the changes are good for everyone.
