precision

My recommedation is to add an api to Cairo to set a color from 8-bit
values. There is a VAST amount of color data in this form, and users are
very interested in getting EXACTLY the same number on the screen.
If this is not done, people will just second guess the float->byte
algorithim and run it backwards to get colors that match the color they
want. This really is a waste of time and it also means that anything you
decide here will be fixed forever, because any changes, even tiny ones,
will break people's reverse-engineered 8-bit converters.
There is no need for 16 bits or any other color data except 8-bit and float.
