fade_from_range - Gradually fades a part of the palette between two others. Allegro game programming

       Gradually fades a part of the palette from the source palette to the dest palette. The speed  is  from  1
       (the  slowest) up to 64 (instantaneous). This routine only affects colors between from and to (inclusive:
       pass 0 and 255 to fade the entire palette).

       Note that this function will block your game while the fade  is  in  effect,  and  it  won't  work  right
       visually if you are not in an 8 bit color depth resolution.
