This enumeration specifies vector fill mode constants. These constants define a winding rule for polygons, that is, which part of a polygon is on the interior.

Values:

IG_VECT_FILLMODE_ODD	Part is filled if a winding number is odd.
IG_VECT_FILLMODE_NONZERO	Part is filled if a winding number is non-zero.
IG_VECT_FILLMODE_POSITIVE	Part is filled if a winding number is positive.
IG_VECT_FILLMODE_NEGATIVE	Part is filled if a winding number is negative.
IG_VECT_FILLMODE_ABS_GEQ_TWO	Part is filled if an absolute value of the winding number is greater than or equal 2.
