This function does two things:

1) Builds a quad-tree under ld->InitialBoundingAreas to achieve good geometry separation for fast overlapping test between triangles and lines. This acceleration structure makes the occlusion stage much faster.

2) Test triangles with other triangles that are previously linked into each tile (LineartBoundingArea) for intersection lines. When splitting the tile into 4 children and re-linking triangles into the child tiles, intersections are inhibited so we don't get duplicated intersection lines.

Test if v lies with in the triangle formed by v0, v1, and v2. Returns false when v is exactly on the edge.

For v to be inside the triangle, it needs to be at the same side of v0->v1, v1->v2, and v2->v0, where the "side" is determined by checking the sign of cross(v1-v0, v1-v) and so on.

Does near-plane cut on 1 triangle only. When cutting with far-plane, the camera vectors gets reversed by the caller so don't need to implement one in a different direction.

(!in0) means "when point 0 is visible". conditions for point 1, 2 are the same idea.

This is the main function to calculate the occlusion status between 1(one) triangle and 1(one) line. if returns true, then from/to will carry the occluded segments in ratio from e->v1 to e->v2. The line is later cut with these two values.

TODO(@Yiming): This function uses a convoluted method that needs to be redesigned.

1) The lineart_intersect_seg_seg() and lineart_point_triangle_relation() are separate calls, which would potentially return results that doesn't agree, especially when it's an edge extruding from one of the triangle's point. To get the information using one math process can solve this problem.

2) Currently using discrete a/b/c/para_e1/para_e2/para_e3/is[3] values for storing intersection/edge_aligned/intersection_order info, which isn't optimal, needs a better representation (likely a struct) for readability and clarity of code path.

I keep this function as-is because it's still fast, and more importantly the output value threshold is already in tune with the cutting function in the next stage. While current "edge aligned" fix isn't ideal, it does solve most of the precision issue especially in orthographic camera mode.
