going to add some internal API to track those such that mistakes

Shapers now can request segmented feature application by calling
add_gsub_pause() or add_gpos_pause(). They can also provide a
callback to be called at the pause. Currently the Arabic shaper
uses pauses to enforce certain feature application. The Indic
shaper can use the same facility to pause and do reordering in the
callback.

monotonic and in which direction. Not sure it's worth it though.

[API] Allow negative font x_scale/y_scale
...
I was reconsidering whether y should grow down, since all three/four
times I've used this API I was tricked and got that wrong in my use.
So I was very inclined to make y grow down instead of up. However,
considering that the font space has y up and it would be very confusing
for callbacks to work against that, I decided that what I really want
is for the user to be able to set y_scale to a negative number to imply
that user-space y grows down.
Changing x_scale/y_scale from unsigned int to int allows that, and I've
made pango to use that instead of negating glyph y_offset later. hb-ft
however still has y group up. I *guess* that's how FreeType works?
I'm not sure, FreeType docs don't make this clear...
I'm happy with the resolution :-).

The idea here is that:
- Like pretty much all other API in harfbuzz, user does not have to

- In any caller code, the case of missing table should be handled
exactly the same way that a too-short table is handled. Turning
a non-existent talbe into a table of size 0 makes the user code
safer.

Also adds --script support to hb-view.
If a script tag is not known to us, we pass the ISO 15924 tag around.
Right now, the OT layer ignores that, but we can fix it to blindly
convert that to an OT script tag.

Let hb_shape() guess script and direction...
...
- Rename HB_SCRIPT_INVALID_CODE to HB_SCRIPT_INVALID
- Add HB_DIRECTION_INVALID
- Make hb_script_get_horizontal_direction() public
- Make hb_shape() guess script from buffer text (first non-common
non-inherit script) if buffer script is set to HB_SCRIPT_INVALID (this
is NOT the default.)
- Make hb_shape() guess direction from buffer script if buffer direction
is set to HB_DIRECTION_INVALID (this is NOT the default.)
- Make hb-view.c set INVALID script and direction on the buffer.
The above changes are meant to make hb-view fairly useful for uni-script
uni-direction text. The guessing behavior however is NOT the default of
hb_shape() and must be asked for explicitly. This is intended, because
the guess is not a suitable substitute to full-fledged bidi and script
segmentation. It's just a testing tool.

Bug 32274 - classic mongolian shaper
...
Add support for classic Mongolian script to the Arabic shaper.
Still work to be done around U+180E MONGOLIAN VOWEL SEPARATOR as it
should not be included in the final glyph stream the same way that
ZWNJ, etc should not appear in the final glyph stream.
But the joining part should be done.
There remains the question of how should the U+18A9 MONGOLIAN LETTER ALI
GALI DAGALGA be handled as it has General Category NSM but a letter
nonetheless. For now, our generic logic makes this a joining T instead
of joining D as other Mongolian letters are.

Invert the mask logic
...
Before, the mask in the buffer was inverted. That is, a 0 bit meant
feature should be applied and 1 meant not applied, whereas in the
lookups, the logic was positive.
Now both are in sync. When calling hb_buffer_add_glyph() manually,
the mask should be 1 instead of 0.

Fix scale issues

hb_font_set_scale() now sets the value to be used to represent a unit
pixel. For example, if rendering a 10px font with a 26.6 representation,
you would set scale to (10 << 6). For 10px in 16.16 you would set it to
(10 << 16). This space should be the same space that the get_glyph_metrics
and get_kerning callbacks work in.

fail, make writable, then start again. That's indeed what the fallback
was doing anyway.

Fix the mystery bug!
...
A couple bugs joined forces to exhibit the mystery behavior of
crashes / infinite loops on OS X / wrong kerning / invalid memory
access. Pooh!
The bugs were involved:
- Wrong pointer math with ValueRecord in PairPosFormat1
- Fallout from avoiding flex arrays, code not correctly updated
to remove sizeof() usage.
We strictly never use sizeof() directly now. And the PairPos code
is cleaned up. Should fix them all. Bugs are:
Bug 605655 - Pango 1.26.2 introduces kerning bug
Bug 611229 - Pango reads from uninitialized memory
Bug 593240 - (pangoosx) Crash / infinite loop with Mac OS X
We were also doing wrong math converting Device adjustments to
hb_position_t. Fallout from FreeType days. Should shift 16, not
6. Fixed that too.
There's still another bug: we don't sanitize Device records
referenced from value records. Fixing that also.

Another C++ strictness fix

Pango Bug 602408 - Invalid C++ code breaks compile with Sun C++ Compiler
(Error: A union member cannot have a user-defined assignment operator)
According to the bug:
C++ Programming Language by Bjarne Stroustrup: Chapter 10.4.12 forbids
explicitly using of union members with constructors, destructors or assignment
operations.
So we use a set() method instead of the assignment operator. Ugly, but hey,
that's life.
