Jan Engelhardt 530e80375e glamor: explicitly draw endpoints of line segments ...

The OpenGL 4.6 specification §14.5.1 "Basic Line Rasterization"
figure 14.2 says:

"""A diamond shaped region of height 1 is placed around each fragment
center; those regions that the line segment **exits** cause
rasterization to produce corresponding fragments."""

As the line does not necessarily exit the last diamond,
it is necessary to explicitly paint a pixel at line ends.
