Any portion of the polygon that is outside the LCD display area will be clipped. The function will also
return, doing nothing, if there are less than 3 vertices.
PARAMETERS
n is the number of vertices
x1 is the x coordinate of the first vertex
y1 is the y coordinate of the first vertex
x2 is the x coordinate of the second vertex
y2 is the y coordinate of the second vertex
... coordinates of additional vertices
