Not necessarily if the generics are properly inlined (perhaps you are
thinking of shared generics).
The range of primary colors is now a generic parameter too. So there
will be tests like "if Color_Range'Last=255 then..." which will be
resolved at compile-time by smart compilers.

Only decoding images of various formats, that's all!

This is not excluded. Probably I'll add an out parameter,
time_of_next_frame, to the Load_image_contents procedure.
