Revert "Zero marks by GDEF for Tibetan"
This reverts commit d5bd0590ae2fbc7b0dee86385a565aef00ffb835.
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:
7e08f1258da229dfaf7e1c4b5c41e5bb83906cb0
So, revert the faulty commit and everything seems to be in good
shape.

[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.

[indic] Improve positioning of post-base bells and whistles
Bug 58714 - Kannada u+0cb0 u+200d u+0ccd u+0c95 u+0cbe does not provide
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.

[indic] Misc harmless fixes!
First, we were abusing OT_VD instead of OT_A. Fix that
but moving OT_A in the grammar where it belongs (which
is different from what the spec says).
Also, only allow medial consonants after all other
consonants. This doesn't affect any current character.
Finally, fix Halant attachment in presence of medial
consonants. Again, this currently doesn't affect any
sequence.
I lied. There's Gurmukhi U+0A75 which is Consonant_Medial.
Uniscribe allows one of those in each of these positions:
before matras, after matras and before syllable modifiers,
and after syllable modifiers! We currently just allow
unlimited numbers of it, before matras.

[indic] Don't apply presentation features across syllables
More like Uniscribe... We still allow user-defined features to
work across syllables, but not pres,blws,abs,psts,etc.
This "regressed" Sinhala numbers by 11. These are cases were
there's Consonant followed by Ra,Halant,ZWJ at the of text.
The Ra,Halant,ZWJ ends up forming reph, which is wrong...
But before we were also ligating that reph with the previous
consonant. That's even more wrong. That's also what Uniscribe
does.

[Indic] Futher adjust ZWJ handling in Indic-like shapers
After the Ngapi hackfest work, we were assuming that fonts
won't use presentation features to choose specific forms
(eg. conjuncts). As such, we were using auto-joiner behavior
for such features. It proved to be troublesome as many fonts
used presentation forms ('pres') for example to form conjuncts,
which need to be disabled when a ZWJ is inserted.
Two examples:
U+0D2F,U+200D,U+0D4D,U+0D2F with kartika.ttf
U+0995,U+09CD,U+200D,U+09B7 with vrinda.ttf
What we do now is to never do magic to ZWJ during GSUB's main input
match for Indic-style shapers. Note that backtrack/lookahead are still
matched liberally, as is GPOS. This seems to be an acceptable
compromise.
As to the bug that initially started this work, that one needs to
be fixed differently:

[Indic] Sort pre-base reordering consonants with post-forms
Before, we were marking them as below-form for initial reordering.
However, there is a rule that says "post consonants should follow
below consonsnts" for base determination purposes. Malayalam has
port-form YA/VA, and RA is pre-base. As such, for a sequence like
YA,Virama,YA,Virama,RA, the correct base is at index 0. But
because the code was seeing RA as a below-base, it was stopping at
the second YA as base, instead of jumping it as a post-base.
By treating prebase-reordering consonants like post-forms, this
is fixed.
MALAYALAM went down from 351 to 265. Other numbers didn't change:

[Indic-like] Disable automatic joiner handling for basic shaping features
Not for Arabic, but for Indic-like scripts. ZWJ/ZWNJ have special
meanings in those scripts, so let font lookups take full control.
This undoes the regression caused by automatic-joiners handling
introduced two commits ago.
We only disable automatic joiner handling for the "basic shaping
features" of Indic, Myanmar, and SEAsian shapers. The "presentation
forms" and other features are still applied with automatic-joiner
handling.
This change also changes the test suite failure statistics, such that
a few scripts show more "failures". The most affected is Kannada.
However, upon inspection, we believe that in most, if not all, of the
new failures, we are producing results superior to Uniscribe. Hard to
count those!
Here's an example of what is fixed by the recent joiner-handling
changes:

Ouch, how did things ever work without this?! The added test that has a

that Win8 shaper has the *exact* same bug / behavior that we used to

Adjust mark advance-width zeroing logic for Myanmar
Before, we were zeroing advance width of attached marks for
non-Indic scripts, and not doing it for Indic.
We have now three different behaviors, which seem to better
reflect what Uniscribe is doing:
- For Indic, no explicit zeroing happens whatsoever, which
is the same as before,
- For Myanmar, zero advance width of glyphs marked as marks
*in GDEF*, and do that *before* applying GPOS. This seems
to be what the new Win8 Myanmar shaper does,
- For everything else, zero advance width of glyphs that are
from General_Category=Mn Unicode characters, and do so
before applying GPOS. This seems to be what Uniscribe does
for Latin at least.
With these changes, positioning of all tests matches for Myanmar,
except for the glitch in Uniscribe not applying 'mark'. See preivous
commit.

[Indic] Don't move virama with left matra
This is important for the Sinhala U+0DDA split matra since it decomposes
to U+0DD9,U+0DCA where U+0DD9 is a left matra and U+0DCA is the virama.
We don't want to move the virama with the left matra.
TEST: U+0D9A,U+0DDA
Note that we were already doing this in the Uniscribe bug compatibility
mode. We now do it all the time.

[Indic] Tamil does not have half-forms either
The Win7 Tamil font does not realy on this behavior, but the WinXP

before base.
WinXP Tamil failures went down from 168964 (15.4752%) to 167
(0.0152953%) (two orders of magnitude reduction!).

[Indic] Implement dotted-circle insertion for broken clusters
No panic, we reeally insert dotted circle when it's absolutely broken.
Fixes most of the dotted-circle cases against Uniscribe. (for Devanagari
fixes 80% of them, for Khmer 70%; the rest look like Uniscribe being
really bogus...)
I had to make a decision. Apparently Uniscribe adds one dotted circle
to each broken character. I tried that, but that goes wrong easily with
split matras. So I made it add only one dotted circle to an entire
broken syllable tail. As in: "if there was a dotted circle here, this
would have formed a correct cluster." That works better for split
stuff, and I like it more.
