Detailed Description

The Graphics2dProxy class is used to draw simple graphics into a rendering device provided by Player using the graphics2d interface.

For example, the Stage plugin implements this interface so you can draw into the Stage window. This is very useful to visualize what's going on in your controller.

Public Member Functions
	Graphics2dProxy (PlayerClient *aPc, uint32_t aIndex=0)
	Constructor.
	~Graphics2dProxy ()
	Destructor.
void	Color (player_color_t col)
	Set the current pen color.
void	Color (uint8_t red, uint8_t green, uint8_t blue, uint8_t alpha)
	Set the current pen color.
void	Clear (void)

void	DrawPoints (player_point_2d_t pts[], int count)
	Draw a set of points.
void	DrawPolygon (player_point_2d_t pts[], int count, bool filled, player_color_t fill_color)
	Draw a polygon defined by a set of points.
void	DrawPolyline (player_point_2d_t pts[], int count)
	Draw a line connecting set of points.
