   Keith wants to be able to support super-luminescent colors,

   API does not allow that. Adding a premulitplied RGBA cairo_color_t
   would do the trick.

   One problem though is that alpha is currently orthogonal to
   color. For example, show_surface uses gstate->alpha but ignores the
   color. So, it doesn't seem be right to have cairo_set_color modify
   the behavior of cairo_show_surface.
