I'm trying to flesh out in my mind the differences/similarities between an image
(Chap. 8 Red Book) and a texture (Chap 9).

Is the glPixelZoom(zoom, zoom) of an image exactly equivalent to a texture (non mipmap) being magnified or minimized? I think I've answered my question because
just remembered about filtering and bilinear filtering with textures. But then
why doesn't images have something similar?

Can an image be rotated like a texture? I assume yes, but all the examples
in Chap 8 have them orientated to the horizon.

I guess in summary does a image and more or less in common with a non
mip-maped texture? Maybe they are really the same, but I'm too bogged down
with details to see.
