That's quite clever, probably incompatible with the new function
(which I guess is why Michael's flagged it), but exposing styles to
the gui_add_to_clipboard function might be a useful addition.

Shame the text styles in IFF FTXT are a load of rubbish/hardly
supported anywhere (the F stands for "formatted", but I've only ever
seen it used for plain text).

There was some discussion recently about new text style chunks. If
it's possible to get the style info out of NetSurf it might be worth
me defining and submitting my own chunk.

I know BeOS was inspired by AmigaOS, but does it use IFF for the
clipboard or something else?
