In fact, any type of baking might have caused holes in mesh. The issue was caused by zspan_scanconvert() attempting to get order of traversal 'a-priori', which might have failed if check happens at the "tip" of span where `zspan->span1[sn1] == zspan->span2[sn1]`. Didn't see anything bad on making it a check when iterating over scanlines and pick minimal span based on current scanline. It's slower, but unlikely to cause measurable difference. Quality should stay the same unless i'm missing something. Reviewers: brecht, dfelinto Reviewed By: brecht Differential Revision: https://developer.blender.org/D2837
