I am happy that you are there right now. This might save my weekend! (-;
Anyway, I just hacked together an impressive example script. One for
the old version which works fine and one for the new version.
I hope I didn't make any stupid mistakes.
PyGL 1.5.7:
#!/usr/bin/env python

def display(*args):
glClearColor(0.0, 0.0, 0.0, 0.0)

glColor3f(1.0,1.0,1.0)
glLineWidth(4.0)
curve=[0.0,0.0,0.0,0.0,1.0,0.0,0.0,1.0,0.0,1.0,1.0,0.0]
glMap1f(GL_MAP1_VERTEX_3, 0.0, 1.0, 3, 4, curve)
glEnable(GL_MAP1_VERTEX_3)
glBegin(GL_LINE_STRIP)
for i in range(0,30,1):
glEvalCoord1f(i/30.0)
glEnd()
glDisable(GL_MAP1_VERTEX_3)
glFlush()
def setup_viewport():
glMatrixMode(GL_PROJECTION)
glLoadIdentity()
glOrtho(-1.0, 2.0, -1.0, 2.0, -1.0, 2.0)
def reshape(w, h):
glViewport(0, 0, w, h)
setup_viewport()
def main():
glutInit('foo')
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB)
glutInitWindowSize(300, 300)
glutCreateWindow('Test')
setup_viewport()
glutSetReshapeFuncCallback(reshape)
glutReshapeFunc()

glutDisplayFunc()
