gifs has a maximum number of colour bits of 8 - ie 256 colors. pngs (and jpg)
can go all the way to 24bit (in fact png can even do 48 bit) ie 16.7 million
colors (or 26.7 million * 26.7million for 48it).
this means gradients get "banded", or you get dirty "dithering" etc. etc. since
there is a limit on the number of colours.
