Paul,

I added the original graphics to data/graphics.

I also reverted the current buildings.png to the previous RGB version. 
This restores some colors to some graphics (noticably Copernicus'
Observatory).

Can you re-add your new graphics to the buildings.png, using the new RGB
format?  You'll probably get slightly better results in your colors (in
most cases the difference probably isn't noticeable).
