[cairo] Bad bug when filling clipped area

[cu]

A bit of a follow-up. The bug occurs when 3rd (last) value X of the
array used to define vertical lines for filled areas is not an integer.
It does not seem to matter what the actual value is, only that it is a
whole vs. fractional value. The bug also requires that the clipped area
have at least one mid-point on the top edge (i.e. top edge is not a
straight line).
