Behdad Esfahbod 02c6c8cd6e Set buffer content type to INVALID in hb_buffer_set_length(0) 
Previously we were only setting this in hb_buffer_clear_contents(),
but set_length(0) is a valid way to reinitialize buffer to use with
new text.

Behdad Esfahbod 71b4c999a5 Revert "Zero marks by GDEF for Tibetan" 
This reverts commit d5bd0590ae.

The reasoning behind that logic was flawed and made under
a misunderstanding of the original problem, and caused
regressions as reported by Jonathan Kew in thread titled
"tibetan marks" in Oct 2013.  Apparently I have had fixed
the original problem with this commit:

  7e08f1258d

So, revert the faulty commit and everything seems to be in good
shape.

Behdad Esfahbod 46a863d91d [indic] Adjust pref reordering logic 
For Javanese (pref_len == 1) only reorder if it didn't ligate.  That's
sensible, and what the spec says.  For other Indic (pref_len > 1)
only reorder if ligated.

Doesn't change any test numbers.

Behdad Esfahbod ddce2d8df6 [indic] Improve positioning of post-base bells and whistles

same results as Windows8
https://bugs.freedesktop.org/show_bug.cgi?id=58714

Test with U+0CB0,U+200D,U+0CCD,U+0C95,U+0CBF and tunga.ttf.

Improves some scripts.  Improves Bengali too, but numbers
are up because we produce better results than Uniscribe for some
sequences now.

Behdad Esfahbod 755b44cce6 [ft] Round metrics instead of truncate 
Lohit-Punjabi has a upem of 769!  We were losing one unit in our
code, and FreeType is losing another one...  Test with U+0A06.
Has an advance of 854 in the font.  We were producing 852.
Now we do 853, which is what FreeType is telling us.

Behdad Esfahbod 9a49351cc2 [indic] Swith pref logic to use _hb_glyph_info_substituted() 
See comments from caveat!  Seems to work fine.

This is useful for Javanese which has an atomically encoded pre-base
reordering Ra which should only be reordered if it was substituted
by the pref feature.
