582069172c Add test case for deleting default ignorables with positioning 2015-07-22 18:44:59 +01:00

8cfbc304ee Fix hide-default-ignorables after f0010dfd01 
We can't delete things before hb_ot_layout_position_finish().  So,
just zero the advance before it, and remove later.

2dbd3d29d6 Fix hide-ignorables if font doesn't have space glyph 
Was broken by 82b521aeb7, as we have
positioning data by then and can't use the output buffer.  Ouch!

9cd59db1af [USE] Implement topographical features for non-Arabic-joining scripts 
This works per-syllable as per the spec, but we think it should be per
spacing/base/??? glyph instead.

29832d797f Route misc untested scripts through USE shaper instead of Indic 
These were never tested with Indic shaper, and indeed wouldn't work there
because they didn't have their viramas and other config defined.  They are
all also supported by MS through USE, so route them there.
