	# The drawing is done through a specialised pen object.
	# There are pen objects for different purposes, this one
	# will draw in a FontLab glyph. The point of this is that
	# Robofab glyphs all respond to the standard set of 
	# pen methods, and it is a simple way to re-interpret the 
	# glyph data.

	pen.lineTo((100, 100))
	
	# Done drawing: close the path
	pen.closePath()

	# go check the font, it should now contain a new glyph named
	# "demoDrawGlyph" and it should look like a square.
