## modelxf4.pi -  
## Test requirements:
##   Test that the modelling clipping indicator is used to determine
##   whether subsequent output primitives will be clipped against the
##   modelling clipping volume during structure traversal.
##   Also verify that the default modelling clip indicator is PIND_NO_CLIP
#  Setup:
#    Open phigs and a workstation, open and post a structure,
#    set up certain clipping volume that should result in partial clipping
#    of the output fill area.
#  Operations:
#    Render a solid fill area using default clipping indicator - PIND_NO_CLIP.
#    Render a solid fill area using clipping indicator - PIND_CLIP.
#    Render a solid fill area using clipping indicator - PIND_NO_CLIP.
#    The first and third fill areas should appear intact, 
#    the second fill area should be partially clipped. 
#  Verifications:
#    verify the existence of pixels at two sample test points
