Comment #1 on issue 19 by moritzka...@gmail.com: Undefined GLUT callback
function Scroll
http://code.google.com/p/glumpy/issues/detail?id=19

it seems that this part in window/backend_glut.py works with the system
macOS glut:
try:
glutScrollFunc = GLUTCallback(
'Scroll', (c_float,c_float), ('delta_x','delta_y'),)
except:
glutScrollFunc = None

but:
146 if glutScrollFunc:
147 glutScrollFunc( self._scroll)

creates the exception.
