Hmm, assume i'd be thinking about a rich text component based on
gecko. It's basically a gtk widget (maybe could be made to draw on a
GdkWindow provided by the hosting application).
Would such a component be possible with the current (and planned goffice)?
What about expose events, would i have to trigger expose in the
draw_cairo() function?
What about printing? It's possible to create postscript output of a
document, but anything more advanced (e.g. rendering a part of a page
for embedding) seems hard.

Thanks for any advice,
Rob
