## viewxf4.pi -  
## Test view index attribute inheritance 
## Test that view index attribute, which is set in a parent structure,
##   is inherited by a child structure. 
## Test that view index attribute, which is set in a child structure,
##   affects the child structure, but not the parent.
## Draw polylines and verify the presence of pixels in the expected locations
