// POLYGON CLASS
//===================================================================
// This does all the basics that a drawn polygon should care about
// NOTE!!!
// When specifying points, the first and last point must be the same
// We are wanting to make sure that when you draw lines the polygon is closed
// MAKE SURE THE FIRST AND LAST POINT ARE THE SAME
//===================================================================
// This draws polygons using the draw function in a realative manner
// so if GL has the matrix moved for the world before calling the draw
// function, then polygon will be drawn relative to the moved location
//===================================================================
