Draw Point (Not in Base Package)

Sets a pixel in a picture to a specified color.

	picture is the collection of drawing instructions to which you add an instruction to set a pixel.
	point(x,y) is the coordinate of the pixel to set in the resulting picture with the origin (0,0) at the top-left corner of the indicator. x is the horizontal coordinate that increases to the right. y is the vertical coordinate that increases to the bottom.
	color is the color of the pixel. The default is black. You can wire a color box constant to this input.
	black in B/W? specifies whether the pixel appears as black or as white if you display it on a black-and-white monitor. The default is black (TRUE).
	new picture is the modified picture.
