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."

Behdad Esfahbod e6c09cdf43 Remove the pre_allocate argument from hb_buffer_create() 
For two reasons:

1. User can always call hb_buffer_pre_allocate() themselves, and

2. Now we do a pre_alloc in add_utfX anyway, so the total number of
reallocs is limited to a small number (~3) anyway.  This just makes the
API cleaner.

Behdad Esfahbod 0b7e4d9f20 [ft] FT_Get_Advance() for advance-width callbacks 
Using graphite2's comparerenderer suggests that this makes hb-ft 15
times faster.  No caching layer needed anymore.

Behdad Esfahbod 4e9ff1dd6e Pre-allocate buffers when adding string 
We do a conservative estimate of the number of characters, but still,
this limits the number of buffer reallocs to a small constant.
