Well, my problem was finding width & height with the proper
aspect ratio, and also big enough to look good (details) and
small enough to look good (not wasting bits encoding too many
pixels). As I didn't kno about the 16x16 stuff, I erred.
But I see the errors of my way now :-)

Thanks a lot for the explanation,
