Yes, you're exactly right Paul. We independently discovered it :-) I've
just implemented a "fp_VirtualContainer" for the overall
hdrftrSectionLayout which has nops for the draw and clearscreen methods.
Thanks to everyone who told me about the right way to C++ design earlier.
I'll commit some code with a some big advances in the
editable header/footer code soon. We will have editable multi-paragraph
headers/footers in V 0.90.

Yes. I think you're right. I guess Eric had not got around to doing this
before he left to run SourceGear. I've had to write a lot of code. Still
the overall idea of shadwo sections for headers/footers works with a bit
of shoehoring I think.

I don't know if I will do this. I might just clip them and let the user
change the margins via pagesetup. Actually we should put some handles on
the left ruler so the user can interactively change margins like the top
ruler.
Anyone interested?

I agree and it wasn't too bad to do.
