Bidi certainly goes well beyond this patch. I don't think you can
actually do the reordering completely at the PangoItem level ...
if I understand the gtkhtml structure 
  
  <text> <image> <text>

Gives you two HTMLText objects not one? But the reordering needs to
be across the whole line of inline objects. (The HTML specs give quite a
bit of detail about how bidi is supposed to work.)

yes, we need to do ordering at object level as well

I don't think getting *display* right for RTL is a huge project if there
was was someone interested in doing the work. Editing and selection
is a bit more of a project. (Much of pango-layout.c is helper functions
for bidi editing.)

yeah, that's what we figured out as well. bidi editing is planned for evo 2.1 so far.
