    Check SAL_USE_COMMON_LAYOUT envar in one place
    
    Makes it easier to flip the switch in the future (or even do something
    more fancy other than checking envvar).

    Validate Kashida positions in CommonSalLayout
    
    Currently checks only for ligatures, but that is a big improvement over
    al code that didn’t do any validation except on Windows.

commit 0762d97cfec60c54fbdb7654ed7843c5b9dfa36b

    Re-enable Kashida insertion in CommonSalLayout
    
    We now do Kashida insertion in ApplyDXArray(), no need for a separate
    step. This simplifies the code greatly (old code is in
    GenericSalLayout::KashidaJustify()).

    Use HarfBuzz shape plan for a bit more control
    
    This way we control exactly what shapers we use in what order, and as an
    extra we can now tell which shaper HarfBuzz ends up using.

    Override GetCharWidths and ApplyDXArray in CSL
    
    A much simpler and saner implementation. This also unbreaks Awami
    Nastaliq.
    
    Break kashida justification, will need to rewrite that one as well.

    Don’t check glyph class unnecessarily
    
    Don’t call hb_ot_layout_get_glyph_class() unless the glyph advance width
    is zero, as we really do not use its result otherwise.

    Cache HarfBuzz font
    
    We now create it only once per physical font, saves us few percents from
    the all over time spent on layout.

    GSoC: Speed up CommonSalLayout by caching hb_face
    
    Cache hb_face so it is not created again and again.
    Switch from GDI to DirectWrite on Windows to obtain SFNT table data.

    GSoC: Enable building Harfbuzz with Graphite
    
    Harfbuzz will now need to be built with Graphite support. This allows
    Harfbuzz to handle Graphite fonts. In case we all building with
    system Harfbuzz, then it should be built with Graphite support else
    we error out.
