I get an error with ST_ModEdgeSplit that looks like aa precision related

When trying to split an edge with a point (the point is from
ST_ClosestPoint, so _very_ close to the edge),
st_modeedgesplit complains that the point is not on the edge.

In fact st_modEdgeSplit doesn't use precision at all
(correct behavior should be : check if point is DWithin edge, project it,
split etc ...)

I'm writting a function rc_ModEdgeSplit that will take into account
