9a9efcff89
This is a large commit. It replaces enriched.distance with factor. Factor is based on integer calculations, calculated in cart_intersect, from the passed robust points, so always trustable. We had to do this because without certain tests failed because of FP problems with distance (calculated with FP). This commit also greatly simplifies relate_collinear, where most things and checks are replaced by simple unified calculations. This is also based on robust fractions (but could have been done earlier). Many (but not all) testcases commented in previous commit are now uncommented again, they now work thanks to the fractions. There are also testcases uncommented which now work correctly using clang/Linux This commit breaks compiling disjoint (because of rescale), and running buffer (also because of rescale), and some more (probably all because or rescaling), this has to be fixed soon after.
