A simple heuristic is used to detect the word beginning and ending by
looking at the word break property value of surrounding characters.
This behaves better than the white-spaces based implementation used before

Introduce QCharAttributes and use it instead of HB_CharAttributes everywhere in Qt
(in Harfbuzz, the HB_CharAttributes is only used in the text segmentation algorithm
which has been moved from HB to Qt (well, most of it)).
Rename some members to better reflect their meaning,
remember to keep HB_CharAttributes in sync with QCharAttributes.
Also replace HB_ScriptItem with a (temporary) QUnicodeTools::ScriptItem struct
that will be replaced with a more efficient/friendly solution a bit later.
The soft hyphen and the mandatory break detection has been factored out
of the default text breaking algorithm to a higher level in order to refactor
the QCharAttributes bitfields and to optimize the implementation for the common case.

to keep them consistent with positions for all other flags.
This changes the internal behavior so that attributes[0].lineBreakType now means
"break opportunity at start of the text (before the first character in the string)"
and is always assigned with HB_NoBreak to conform rule LB2
(see http://www.unicode.org/reports/tr14/#LB2).
The current implementation is based on the sample implementation from tr14
that aimed to be as simple as possible rather than to be optimal.
From now, we can use pieces of the attributes array "as is"
without having to adjust some positions. Or we can analize some long text
by chunks (e.g. paragraph by paragraph) and consume less memory.
This introduces a minor overhead that will be eliminated shortly.

This is a work-around for a feature missing in Harfbuzz that
can make a text run that contains a surrogate and a ligature
crash. This will potentially cause the ligatures to break up
if you combine them with a surrogate, causing visual changes
to the text, but the scripts that require GSUB should not be
affected by this, since they will not use surrogates. Still,
it's not a permanent fix, but will serve as a bandaid for the
crash until the underlying problem has been fixed.

there are several reasons to do this:
* text breaking is not a shaper's job;
* since the text breaking rules are bound to a specific Unicode version,
updating Qt's internal unicode data would require updating the data in HB as well;
* makes porting to HurfBuzz-NG some easier

As in other shapers, we need to make sure that the default
attributes of the first character is set before doing the
greek-specific composition (which will set the attributes
for characters > 0). The effect of this would be that
the clusterStart did not default to true in the start of
the string, and we would get an unexpected situation
in addNextCluster() in QTextLayout which would cause an assert.
The example in the task, which combines a greek polytonic
(dasia-oxia: u1FDE) with a regular combining diacritic
(asterisk under: u0359), is not a correct string, but should
not cause an assert.

The mechanism in fontconfig which determines if a certain character
is available (FcCharSetHasChar()) may give false positives, in which
case we would load and unload those fonts per every char for which
FC gave us a false positive. This was a major performance regression.
Specifically the false positives happened when looking at e.g.
italic variants of certain multilingual fonts, since we only check
the charset of the font family as a whole and not of the specific variant,
which may only support a subset of the chars.
To optimize this, we remove the deletion of the font engines after
loading them, but also wait with loading the opentype tables until
they are actually needed. This means that for the false positives,
we will load the font, but the cached data for each unused font will
be much smaller.

Thai is not supposed to have ZWJ and ZWNJ characters or any other of the
Inherited Unicode Scripts
(http://www.verisigninc.com/assets/idn-inherited-unicode-script.pdf)
- they don't have a mapping to the thai encoding tis620 which libthai
requires. However it is an unfortunate fact that there are many websites
etc that liberally place these ZWJ and ZWNJ characters throughout thai text
to force word boundaries, so we must also deal with them.
We deal with all Inherited characters by mapping them to the invalid code ~0
in tis620 encoding, following what libthai does internally in its own tis620
encoding functions, and then replacing this character with the original
unicode and setting dontPrint to true to hide the ZWJ and ZWNJ
characters.
Includes a unit test to check the behaviour.

This was an obvious typo - a missing "else" in a group of if statements.

Some Thai characters with two above glyphs were higher than fonts ascent. This
caused them to be clipped in for example qtcomponents buttons.
Added checking for this and calculation of new lower offset between glyphs if
needed.

Sometimes GPOS tables are used for kerning and can grow quite
large if the font is unoptimized. In that case, allocating the
maximum size for each ValueRecord will have a great impact on
memory consumption. For GPOS tables which do not contain device
tables, we only allocate the memory actually need to store the
data instead.
While it would be possible to optimize memory for GPOS tables that
contain device tables as well, this is not a part of this patch.

Since 5e07a3ac58f93bd5e09715d43b58c20950c2befa Thai text layout is
handled by libthai to special case of the SARA AM. It didn't handle
isolated SARA AM. This patch fixed it and added detailed explaination
on the special case.
The dotted circle should be shown rather than hidden.
Add an test case to verify that with Waree.

These comments were mostly empty or inaccurate. Appropriate naming of
tests and appropriate placement of tests within the directory tree
provide more reliable indicators of what is being tested.

This patch is contributed by Thanomsub Noppaburana from libthai. It
added a special thai shaping function to handle SARA AM character
for fonts without OpenType rules to support it, like Nokia Pure Text
AS.
With modification to logClusters assignment to make sure that
QTextLine::glyphRuns(int from, int length) returns correct glyphs.
