void glPlotPolygon(int n, int y1, int x1, int y2,
int x2, ...);
Plots the outline of a polygon in the LCD page buffer and on the LCD if the buffer is unlocked. Any
portion of the polygon that is outside the LCD display area will be clipped. If fewer than 3 vertices are
specified, the function will return without doing anything.
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.

void glFillVPolygon(int n, int *pFirstCoord);
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. If fewer than 3 vertices are specified,
the function will return without doing anything.
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.
