[FriBidi] Is it possible to disable the shaping to presentation forms

[eduardo]

That might the answer to my opening question. But unfortunatelly I 
don't know how to use the levels to reorder the runs. Is there any 
documentation?



Wouldn't it be easier to let fribidi to do all the work except the 
shaping, and then let harfbuzz to shape everything as it was LTR?

Then the clusters would be something like:

cluster[i] = fbd_v2l[glyph[i].cluster]

and the bidi types would be

bidiType[i] = fbCharType(cluster[i])
