+Overloaded method which adds support for the non-zero winding rule.
+</short>
+<descr>
+<p>
+Polygon is an overloaded method in TLazCanvas. It provides support for the 
+non-zero winding rule in the polygon fill operation.
+</p>
+<p>
+The overloaded variant extends the method from TFPCustomCanvas to include the 
+Winding argument used in the DoPolygonFill method. When Winding is set to 
+<b>True</b>, DoPolygonFill calculates the winding number for the sorted 
+vertices on the polygon and calls DrawPixel to apply the brush color needed 
+for the pixels inside the winding path.
+</p>
+<p>
+Polygon updates the internal member used to store the value in Winding, and 
+calls the inherited method in TFPCustomCanvas where the brush and pen colors 
+are used to draw the polygon represented in Points.
