PixelDisplay.pixel returns the color of a specific pixel within the display.
|Parameter Name||Type||Default Value||Meaning|
|x||number||0||horizontal coordinate of pixel to get|
|y||number||0||vertical coordinate of pixel to get|
Note that the color is always returned with the alpha channel included. So even if you draw in color "#00FF00" (solid green, with alpha implied), the pixel color will be returned as "#00FF00FF" (also solid grean, but with the alpha explicit as the final FF).
