multiple intersections not found by shm

This can cause mesh leakage. Problem 1: triSurfaceSearch::findLineAll does not increase starting point after finding hit. This should not be needed since any previous intersections are excluded through the shapeMask. Problem 2: fast triangle-bounding box calculation misses some intersections.

boundBox2.tgz

Attached a little test program. It explicitly does an intersection of a single boundbox with a single triangle. The optimised routine (using intersections of 4 axis aligned rays) does not find intersection, the explicit one (intersect with all 12 edges separately) does.

presumed to be resolved considering the addressed commit.
