That's a very good question.  I don't know the answer.

Well...  There are the scheme reports which form a scheme structure
that uses the stylesheets to convert everything into HTML.  This HTML
is then fed into GtkHTML for display.  GnuCash also adds hooks to
GtkHTML to handle the GoG images and back-calls for things like
opening up account registers or looking at invoices by clicking on
hyperlinks in reports.

Well...  We've discussed other options.  One potential approach is to
change out GtkHTML for something like Gecko.  Granted, this would add
a build dependency on Mozilla, which might suck for those building
from sources..  But it's at least something to think about as an
option.  I have no idea how that would affect building on Win32 or
Mac.  But if you want to look into that (or other HTML renderers), I'd
certainly encourage you!  As would other devs!  :)
