Alt Wind

Notes: This Program shows the differences between the Alternate and Winding fill modes in windows. The shapes are drawn by the Polygon() function and what areas of that figure get shaded is determined by the fill mode. Both shapes are made from three overlapping triangles. The left shape uses the alternate fill mode and has two white squares where the rectangles overlap. The right shape uses the winding fill mode and only has one white square where the rectangles overlap.
