// BONE_VISIBLE test whether vertices of mesh are "visible" to a given bone,
// where "visible" is defined as in [Baran & Popovic 07]. Instead of checking
// whether each point can see *any* of the bone, we just check if each point
// can see its own projection onto the bone segment. In other words, we project
// each vertex v onto the bone, projv. Then we check if there are any
// intersections between the line segment (projv-->v) and the mesh.
//
// [flag] = bone_visible(V,F,s,d);
//
// Input:
// V #V by 3 list of vertex positions
// F #F by 3 list of triangle indices
// s row vector of position of start end point of bone
// d row vector of position of dest end point of bone
// Output:
// flag #V by 1 list of bools (true) visible, (false) obstructed
//
// Note: This checks for hits along the segment which are facing in *any*
// direction from the ray.
