Regressed with a1714c84f245beb182a2221a1832b041788af200 and ab9a897b688e991a8405cf938dea9d6a2f1ac072, which removed the handling for value records that specify an device advance tables but do not actually have an offset for it. Previously HB_OPEN_Get_Device handled this through the HB_Device being allocated as structure and zero initialized. Now this case is represented by a null pointer HB_Device, which we must handle.

2010-05-27use unsigned char instead of unsigned in the bitfield.Lars Knoll1-12/+24
This saves significant memory, as the HB_CharAttributes and HB_GlyphAttributes structures are not 4 byte aligned anymore, by aligned to 1 resp. 2 bytes. The change is not compliant with ISO C, but accepted by almost all compilers.

2010-04-14Fix a bug in malayalam shapingLars Knoll3-28/+52
See http://bugreports.qt.nokia.com/browse/QTBUG-1887. We were not finding the base character correctly in the case where the syllable contained a ZWJ. In addition, the indic OT specs require us to also apply the 'loca', 'cjct' and 'calt' features. They seem to be mostly unused by todays fonts, but we should better apply them anyways.
