When used with P3D, strokeWeight does not interpolate the Z-coordinates of
the lines, which means that when rotated, these flat lines may disappear.
(Since, uh, lines are, you know, flat.) The OPENGL renderer setting does
not share this problem because it always draws lines perpendicular to the
screen (which we hope to do in a future release).

One solution to this might be to follow OpenGL's lead (at least in some
implementations) and handle strokeWeight() after the perspective
transformation is already applied, generating the quad so that it's the
appropriate size in screen coordinates.

yeah, and now that the line/poly/point code is broken up a bit, this might
be a little more doable.
This bug is now being tracked here.
