No, there is no persistent form. Or, to use a better word, a "fixed" 
form.

Let's assume for a moment that I have to keep the otherwise temporary 
multiple-layered version of an image. Then I want to know which if the 
following I must also keep:

	a) Several times while editing an image, I save. Each new save is
	   clearly a derivative work of the previous save. Do I have to
	   keep every save as source?

	b) (a), but for C source

	c) When editing a file in vim, I often create multiple panes. Much
	   like having multiple layers in an image, it eases editing. That
	   set up would probably be useful to anyone else who is modifying
	   that file. Normally these panes are destroyed when I dispose of
	   the editor window. Are they source?

	d) I also use syntax coloring when editing code. If I use my own
	   custom syntax coloring, is that part of the source?

I'm particularly interested in how (a) and (b) are any different.
