[AD] palette_color[] in 8 bit modes

Hi,

The docs for the palette_color[] array (alleg012.html#palette_color) 
state that in 8 bit mode the array indices map onto theirselves (ie. 
palette_color[i] = i for 0 <= i < 256).

The attached test program, for me at least, shows that the palette_color 
array is all 0 in 8 bit mode, which is nasty :-(

Please confirm whether this is either a bug in the library, the 
documentation, or my interpretation thereof. Thanks!

Bye for now,
