#15271: TINYGL: glPolygonStipple seems to work when looking at one side only

Reporter:  neuromancer  |      Owner:  (none)
    Type:  defect       |     Status:  new
Priority:  normal       |  Component:  Graphics
 Version:               |   Keywords:  tinygl
    Game:               |
------------------------+----------------------
 When using the combination between polygon stipple and polygon offset in
 the Freescape games (which is used to create the patterns): the triangles
 tend to be invisible, when you change the perspective a little bit. But
 there is something else, that is curious. In a symmetrical room, one side
 looks good and the other looks broken. (check the screenshots). Reversing
 the perspective changes the sides, so it looks like the rendering is
 correct is always in the same side so I suspect this is an issue in TinyGL
 since the same code works fine for OpenGL/shaders.
