1. Colors?
Yeah, with this mailing list, we feel like we aren't alone, but, this is
my doubt: with the routine mask_image (thanks to Mike Fowler!) I can mask a
color of background of my sprite, but this routine can do it with 256
colors mode? In a image that has 256 colors? (this is to you Mike...)
Awaiting answer...

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 :)
