That is exactly what I am trying to eliminate. The best solution so far
results in a 9.7M tga file at level 6 compression -- whatever GIMP means
by 6. However it is some five times faster to render than a random
generation of many fewer stars. However it is a poor solution in general
as it still requires odd things to be done.
