righto...

masked_image is just display_image, but instead of printihg the image
line-by-line, it checks each pixel to se if its the colour that you want
to mask. If it is, it moves the draw position 1 pixel to the right
WITHOUT drawing a pixel, so that peice is left clear.

so, i figure, if display_image can do it, masked_image can do it (but
its alot slower because it has to scan each pixel, then either draw it
or move on)

hope that answered your question :)
