[HarfBuzz] glyph moving across syllable boundries

[Sne Kore]

Hi,

     We are currently working on lohit2 project . As in reference the
preceeding link can be useful [1].

     We came across bug for the word "vidarbha" . We have tested this word
on windows as well . This word is working properly on
windows environment but not on the harffbuz platform. The screenshots for
the word "Vidarbha" on windows[2] as well as on harfbuzz platform is been
provided at link[2].

      To reproduce lohit devanagari ttf [4]
./hb-view Lohit-Devanagari.ttf विदर्भ

     I Think the basic problem is rphf glyph from last syllable is getting
joined with the first syllable. Uniscribe seems to handle this properly.

Thanks & Regards,
Sneha Kore
