Nikhila Ravi 23279c5f1d Utils for clipping mesh faces partially behind the image plane 
Summary:
Instead of culling faces behind the camera, partially clip them if they intersect with the image plane.

This diff implements the utils functions for clipping.

There are 4 cases for the mesh faces which are all handled:

```
Case 1: the triangle is completely in front of the clipping plane (it is left
        unchanged)
Case 2: the triangle is completely behind the clipping plane (it is culled)
Case 3: the triangle has exactly two vertices behind the clipping plane (it is
        clipped into a smaller triangle)
Case 4: the triangle has exactly one vertex behind the clipping plane (it is clipped
        into a smaller quadrilateral and divided into two triangular faces)
```
