Plots the outline of a polygon in the LCD page buffer and on the LCD if the buffer is unlocked. Any por-
tion 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.
y1
is the y coordinate of the first vertex.
x1
is the x coordinate of the first vertex.
y2
is the y coordinate of the second vertex.
x2
is the x coordinate of the second vertex.
...
are the coordinates of additional vertices.
RETURN VALUE
None.

Fills a polygon in the LCD page buffer and on the LCD screen if the buffer is unlocked. 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.
*pFirstCoord
is a pointer to array of vertex coordinates:
x1,y1, x2,y2, x3,y3,...
RETURN VALUE
None.
