separate groups. The section is swept normal to the trajectory, producing a mesh. I'm doing the triangles only now, not copying over any entities. Also fix a bug in the PNG export; rows are 4-aligned, so that was breaking when the width of the image wasn't divisible by four. Also fix a bug in lathes, where it generated overlapping triangles for one segment. And change the groups to record both "this mesh", the contribution due to the extrude/lathe/whatever, and the "running mesh", that we get after applying the requested Boolean op between "this mesh" and the previous group's "running mesh". I'll use that to make step and repeats step the mesh too. [git-p4: depot-paths = "//depot/solvespace/": change = 1801]
