A utility function for drawing vector diagrams. Draws two line segments to indicate the angle between two vectors, typically used for indicating orthogonal vectors are at right angles in 2D and 3D diagrams.
corner(p1, p2, p3, d = 0.1, absolute = TRUE, ...)none
Starting point of first vector
End point of first vector, and also start of second vector
End point of second vector
The distance from p2 along each vector for drawing their corner
logical; if TRUE, d is taken as an absolute distance along the vectors; otherwise it
is calculated as a relative distance, i.e., a fraction of the length of the vectors.
See pointOnLine for the precise definition.

In this implementation, the two vectors are specified by three points, p1, p2, p3, meaning
a line from p1 to p2, and another line from p2 to p3.
