Behdad Esfahbod 738d096a06 Pass through unknown ISO 639-3 language tags to OpenType engine 
In hb_ot_tag_from_language(), if first component of an unknown
language is three letters long, use it directly as OpenType language
tag (after case conversion and padding).

Behdad Esfahbod 290e3ee517 [graphite] Only pass the first part language tag to graphite 
Still not sure about:

1) Case.  We pass lowercase for now.  Would be nice if graphite was
uppercase 3letter like OpenType,

2) Padding.  IMO, tag padding is always with spaces, but Martin was
talking about NUL bytes.

Behdad Esfahbod 4c9fe88d30 [API] Make all _from_string() functions take a len parameter 
Can be -1 for NUL-terminated string.  This is useful for passing parts
of a larger string to a function without having to copy or modify the
string first.

Affected functions:

	hb_tag_t hb_tag_from_string()
	hb_direction_from_string()
	hb_language_from_string()
	hb_script_from_string()

Behdad Esfahbod a499bdea5c [graphite2] Bail if grface is NULL 2011-08-25 22:46:21 +02:00
Behdad Esfahbod 3007ffa9e5 Reorder combining-class to better suit Arabic shadda mark-mark positioning 
As reported by Khaled on the list:

"After the introduction of canonical reordering of combining marks
(commit 34c22f8), I'm no longer able to do mark/mark substitution or
positioning for mark sequences that involve shadda as a first mark (or
most interesting sequences at least).

"After some digging, it turned out that shadda have a ccc=33 while most
Arabic marks that combine with it have a lower ccc value, which results
in the shadda being reordered after the other mark which,
unsurprisingly, breaks my contextual substitution and mkmk anchors."
