nbv d07a6c39cf 0027930: XMT file conversion loops infinitely
Now, the algorithm tries to estimate U- and V-ranges of future intersection curve(s) on the surface. This information is used in stop-criterium of the algorithm instead of full surface range used earlier. It allows reducing dependencies of intersection result on the surface ranges.
