Unacceptable. That means I have a 8bit paletted image, instead of an actual
greyscale image. Theres a bunch of reasons why this is bad, including needing
to load four bytes instead of one (pixel value (as pallete entry) and r, g, b, instead of just the pixel value (as intensity)); and the fact that I no longer
have any easy way of knowing its greyscale (I already hashed this out with LIM
on irc, and there just isnt any easy way of doing this that squashes most/all
corner cases.)

What I want to do is extend the SDL api to allow 8bit greyscale, instead of
screwing around with paletted surfaces.

I'm hoping for a responce from Sam, actually.
