示例1: drawLine

// this test draws lines of different lengths and compares
// them with pixel placement
// grey pixels denote start and end of the white drawn lines
// black pixels only make those grey points better visible
// yellow and magenta lines should start and end next toa black pixel,
// yellow one right to the last black pixel down, magenta below the last
// black pixel to the right
// white lines are always double drawn, lines back and forth.
