Fallback to Latin script if the font has no other usable scripts
...
Patch and description from Jonathan Kew:
It turns out that some legacy Thai fonts provide OpenType substitution
features to implement mark positioning, but (incorrectly) put those
features/lookups under the 'latn' script tag instead of using 'thai' (or
possibly 'DFLT'). See
https://bugzilla.mozilla.org/show_bug.cgi?id=719366 for an example and
more detailed description.
Although this is really a font bug, I suggest that we could improve the
rendering of such fonts by looking for the 'latn' as a fallback if
neither the requested script nor "default" is found in
hb_ot_layout_table_choose_script. Suggested patch against harfbuzz
master is attached.
This does _not_ affect the other kind of legacy Thai font, where custom
code to support vendor-specific PUA codepoints would be needed. I'm not
keen to go down that path; IMO, such fonts should be ruthlessly stamped
out in favour of standards-based solutions. :)

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.

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.
