Behdad Esfahbod 54d1a0d2b2 Form clusters before ensuring native direciton
This is essential as ensure_native_direction uses cluster info that
is set by form_clusters().

Behdad Esfahbod 5157e12a55 Rename HB_UNICODE_GENERAL_CATEGORY_COMBINING_MARK to HB_UNICODE_GENERAL_CATEGORY_SPACING_MARK
Spacing_Mark is the current Unicode long-name for this property value.
The previous name was wrongly carried from glib.

Behdad Esfahbod f6fd3780e1 Let shapers decide when to apply ccmp and locl
Instead of always applying those two features before the complex shaper,
let the complex shaper decide whether they should be applied first.

Also add stub for Indic's final_reordering().

Behdad Esfahbod c4641723fb [API] Add compose() and decompose() unicode funcs, rename other ones
Add compose() and decompose() unicode funcs.  These implement
pair-wise canonical composition/decomposition.

The glib/icu implementations are lacking for now.  We are adding
API for this to glib, but I cannot find any useful API in ICU.
May end of implementing these in-house.

Changed all unicode_funcs callback names to remove the "_get" part.
Eg, hb_unicode_get_script_func_t is now hb_unicode_script_func_t,
and hb_unicode_get_script() is hb_unicode_script() now.

Behdad Esfahbod b70c96dbe4 Enable applying GSUB/GPOS features in multiple segments
Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=644184
among others.

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.

Nothing functional in there yet.

So far, we're parsing IndicSyllabicCategory.txt and IndicMatraCategory.txt
fils from Unicode Character Database and store them in an array to be used
by the shaper.  Also hooked up the shaper, but it does not do anything
right now.

Behdad Esfahbod 7403e055cd [Vertical] fix vertical gpos
Wow, it took me a few days to find the right fix!

We now set the advance for attached marks to zero, but we
do this in the _finish() state of gpos, so it shouldn't
regress with fonts like DejaVuSansMono that explicitly
decrease the mark advance width to set it to zero.

Behdad Esfahbod 0fd8c2f1be [API] Make get_glyph() callback return a boolean
We need to know whether the glyph exists, so we can fallback to
composing / decomposing.  Assuming that glyph==0 means "doesn't exist"
wouldn't work for applications like Pango that want to use different
"doesn't exist" glyph codes for different characters.  An explicit
return value fixes that.
